^good job stealth!!!
I dont think there are gains from an intake just yet.
do some porting and polishing and head work, then worry about feeding the engine MORE air.

my DIY deleted resonator cold air intake is EXACTLY like the AEM v2, minus the shiny aluminum.

i think the stock throttle body is the bottle neck.
no point in upgrading to a intake if the throttle body is the restriction.

Ive bored my throttle body and have ported and polished intake manifold.
a 4 inch intake would be beneficial to me

What about the rest of the exhaust?? How much gain with opening up the exhaust all the way back (of course I am going to keep my beloved quad 4 exhaust tips and have them welded on!

My TL-S is running very well right now, when I get on it - it has a good sound, a bit more volume and air flow sound, you can hear it when accelerating, but at idle is stock sounding. Absolutely no drone with the high flow cats, and j pipe.

I will have to consider porting & polishing , but am clueless about this, only have heard about people doing it to ...

if you get a catback* you will further open up the exhaust! which is a good thing!

these are my mods and the order I did them.
1)jpipe.
2)pre-cat deletes
3)ported polish intake manifold and bored throttle body
4) DIY resonator delete cold air intake mod
5) rv6 catback exhaust

pretty much bolted on. im missing a few bolt ons like a light weight pulley and a few other minor mods

StealthTL-S

Well, I have done # 1 and # 2 on your list.
I would love that rv6 exhaust, but I want to keep my stock type S tips. Is this possible?
and the sound - how will the sound / volume change if I add a catback??

justnspace

iTrader: (1)

^yeah, if you hack up the catback exhaust, butt, lemme tell you this...after spending the money on it, I WOULDNT WANT TO HACK IT UP!

EvilVirus

iTrader: (8)

Dont do this again civic dude........look since you like your tl-s exhaust tips then why dont you have a shop fab you up an exhaust system to your liking while keeping the tips.

Anything is possible.

If you really want an aftermarket one like RV6 then dont hack it up for some tips that absolutely does nothing for you.

^its like he gets smart for like 2 minutes and then gets dumb for the rest of the day

Nick216

Rv6 tips look just like type s, if not better. If the stupid tips are stopping you from getting one of the best mods we can have. Idk what to say.

iTrader: (5)

i don't really see any difference between the xlr8 quad tips vs the stock tips. i do see a difference between the rv6 and the stock tips (one of the reasons, not the major reason, i went with xlr8 instead).

opening up the exhaust will definitely help!
here's my mods and the order:

1. jpipe and quads
2. hfpcs
3. aem v2
4. hfc (3rd cat)
5. larger resonator
6. bored tb, port and polished lower runners, "port and polished" manifold (did it my self in 4 hours after i was sold a PnP IM that did NOT fit and i had to drive to work the next day...i didn't do a great job)
7. flashpro tuning the whole time

^ She must be breathing pretty damn good.


What porting angle did you go with on the heads?


edit-


sorry misread

FamilyGuy

I hear ya. I know all the arguments from both sides on CAI dynos, and I dont want to derail this thread.

Let's just say I choose to believe it makes a difference

I agree with justnspace that the TB is the bottle neck and without a larger TB the diff of a CAI is minimal. However, keep in mind it all works together, so as you open up the exhaust any restrictions in the intake will be amplified. Yes, the TB is the bottleneck and yes the stock intake is good, but it still has restrictions. It has a lot of turns/corners, it's designed for quietness (usually at the cost of performance) and has a standard paper filter not to mention the wall of plastic that the air sees as soon as it goes through the filter, before it has to turn nearly 90 degrees towards the TB, followed by the accordion/ribbed section, great for turbulence.

StealthTL-S

You sober up you drunkin fool Justnspace..you stay drunk all day, so sober up just 2 minutes a day when you write here ok, it's ok for you just to put down the bottle when you write here, ok ..

Anyway,
I like the idea of getting a custom exhaust like heavenly virus said. That way I can save some money compared to the super expensive RV6 dual exhaust = money! And, I like the size of the type S quad tips, what are they like 2 1/2 "? I don't like 3-4" tips, they are just too big for me.
Or, can I find a cat back without such big tips?

- Nobody has told me what sound I am going to have with the added cat back with my setup. I don't want it too loud on the insterstate. It is still my luxury TL-S even now

EvilVirus

iTrader: (8)

Come on dude use some common sense. This forum is full of threads that have ask that question. Reduce sound be adding resonator (research when the time comes or even now on which one will suit you best). No one can tell you what sound you are going to get because no one knows the route you are taking. Youtube and/or search the forum one countless of threads that people have posted about the same thing you are asking again. Look like I stated before, custom exhaust or if you go aftermarket; there is another option. You can find a use and cheap one in the black market and hack that one to install your oem quads.

StealthTL-S

Dude,
I might just have to visit the exhaust shop like you are saying, I can keep my quad type S tips, I like the OEM type S look. I am now searching the threads on ATLP quad exhaust and XLR8 quad exhaust, and RV6 dual quad exhaust checking on the sounds.........thank you 'heavenly' virus for your common sense.

^so.....

how do you like the HFC and jpipe?

StealthTL-S

It's ok, I like them. A little extra sound, good sound, no drone or rasp. I guess, a little performance increase down low - mid range. No dyno, so I don't know for sure. I like it, but kept my oem parts just in case. $1000.00 for these mods for the amount of gain, is questionable to me. $1600 for a cat back is very questionable for me. Overall, I do like the combination of high flow cats, j pipe, and type S oem exhaust, sounds good, looks oem, which I like.

It's because you want to be spoon fed answers, the answers are already here, all you have to do is search.

StealthTL-S

Look here man, I don't need to be spoon fed answers, since you are so strong with your words I have to tell you I don't respect answers here much. They are from some people that are 20 years old that ruin their cars. They add modifications that decrease the value of the car. They ruin the luxury of the car. They take a nice car and make it a ruined vehicle. What happens when you go to sell your TL with all the modifications, you going to put all the stock parts back on?
Look how many people have had problems because they modified their vehicle and now they have problems. It is all over the site. You think I want to listen to somebody that has modified their car and now has problems. You think I want to listen to a 20 year old that has a loud exhaust that bothers the neighbors or attracts local police?
I search , but I don't agree with some of the mods. I don't have the same goals with my TL-S that many here do.
First off, I don't want to ruin the luxury of my TL-S. Second, I don't want bring attention to my car (noise). Third, I want to keep my TL-S with a stock / Oem appearance, so any mods will not be apparent , such as a cat back that does not look stock. I don't want any drone or rasp , whatsoever, this ruins the car in my opinion. So, you can tell me to search, but the answers I find , many are not with the same goals I have. I get better advice from my mechanic at the import speed shop where I had my high flow cats put in. He is married with a family and told me not even to mod my TL-S at all. See, a different line of thinking. So, you see, the answers are not all here! But, some members here have been very helpful to me, and helped me solve some problems, I must note that.

Nick216

Modding cars is a hobby. Why would I want a car that looks the same as everyone elses. And you just considered buying a custom exhaust, and now your saying exhausts ruin the car. I don't get you. but maybe because im 20 years old idk what im saying

StealthTL-S

To each's own man, but some exhausts in my opinion do ruin the car. Others, sound very nice and are really nice on a car. It just depends on the person. I don't like loud exhausts, but many here do. I am considering a custom exhaust , but I am close to believing ANY exhaust other than stock will give you some drone or rasp in your car when driving in 6th gear on the interstate and I don't want that. I go on trips on the interstate and I like having a luxury vehicle then! I also agree Modding is a hobby, I have done it for years, back when I had a Honda CRX, people just change. When I was 20 I had a custom exhaust that was so loud it vibrated in the floorboard! I had to change it out.

At all these assumptions.

Good luck on your quest, sir.

Not everyone here is an idiot. Try respecting the people trying to help you and peoples' different taste and you might get some helpful answers.

FamilyGuy

Just do it already :P

If its too loud or too much drone for your taste, throw in a bigger resonator until you're happy.

On intakes: http://www.isuzuperformance.com/isup...ch/intake.html

OEM

The original equipment intake system on a car consists of a resonator, lots of plastic duct work, a large metal or plastic air filter canister, a paper air filter element, and a rubber accordion hose between the filter canister and the throttlebody. Most often, the intake system will pick up air from behind the fender or bumper, from the very end of the plastic duct work and resonator. If this is the case, this is advantageous because cooler air allows the engine to make more power than hot air, as the air inside the engine compartment.

However, there are several disadvantages to the OEM intake system.
The resonator and the plastic duct work can be very restrictive to air flow. These pieces are designed to reduce intake sound, and performance is not the greatest concern. removing the resonator and enough of the duct work such that the system still pulls in air from behind the bumper or fender can do a great deal to improve air flow.
The paper filter element is designed with money as its chief concern. Paper does not flow as well as cotton gauze or cloth, as is used with aftermarket performance drop in filters, such as those made by K&N. These filters provide a great deal more air flow with the added advantage that they are reusable and can be washed, reoiled, and reinstalled lasting over ten years, as opposed to the paper filters which are thrown away every year or two with proper maintenance.
The filter canister itself often has inlet and outlet passages that are quite small and constrictive, but eliminating this restriction is a bit more involved and will be discussed in the next several sections.
The accordion hose between the filter canister and the throttlebody does not encourage very good air flow. The ribs of the hose extend into the air flow and cause turbulence, reducing flow. Eliminating this restriction will also be covered in the next several sections.

Cold Air Intake Systems

A cold air intake system is named such because it draws air in from outside the engine compartment where the air is comparatively cold as compared to the hot air inside the engine compartment.

The most common and most effective design is to use sections of mandrel bent pipe, connected with turbo hose connectors, leading from the throttlebody leading out of the engine compartment to the area behind the bumper or behind the fender, where a cone filter is fitted to the pipe to draw in cool air from outside the engine compartment. The combination of the cooler intake air and the reduction in flow resistance results in significantly higher power improvement than any of the other intake systems discussed here. In addition, the intake system will typically be three or more feet in length, tuning the intake charge and effectively acting as an extension of the intake manifold of the engine, almost as if it were a header for the intake side of the engine, improving low and mid range torque. If all this weren't impressive enough, the added length of the pipe work also encourages something called "laminar air flow effect" whereby the air passing through the pipe is unobstructed and begins to act somewhat more like a liquid than a gas, gaining momentum as it passes down the pipe and resisting anything that would stop its flow, acting with a air ramming effect as it passes through the throttlebody.

Somewhat less common are cold air intake systems made up of dryer hose and other materials. Dryer hose has ribs in it and much like the accordion hose discussed earlier, it causes turbulence and resistance in the air flow, negating any of the laminar air flow effect.

There are few, if any, disadvantages to the mandrel bent pipe cold air intake systems. The air intake point is typically lower than the OEM system, meaning that the car can not be driven though deep standing water (puddles or streams deeper than a foot) and there should be a provision in the design for a splash guard to keep water from being thrown off the tire and onto the filter.

Testing by Sport Compact Car and Import Tuner Magazines showed 9-13 HP improvement in engine performance from this type of intake system, with no difference in performance if the hood was open or closed or if the vehicle were moving or not.

Some will claim that heat from the engine compartment will be transferred through the pipe of the intake system and into the air passing through the pipe, but this is not true. Testing by Sport Compact Car showed negligible change in intake temperature between where it enters the filter and when it passes through the throttlebody. Their conclusion was that the air is passing through the pipe at a high enough speed that it does not have time to pick up any heat from the pipe itself. Further evidence of this is the fact that the Ice Man brand intake system, made of heat insulating PVC plastic, tested at 9 HP while the AEM brand intake system, made of heat conducting aluminum, tested at 12.9 HP. The conclusion is clear that the design of the intake system is more important than what type of pipe is used to make the intake system.

StealthTL-S

I have to say I am very satisfied running the RV6 HFPC's and RV6 V3 jpipe. I am running them with the stock Type S quad exhaust. I really like the setup, sounds very good, a little more volume, feel some gain and response through the band, and a satisfied with leaving it like it is.
I am thinking most about getting a Flashpro tune next. Less possible considerations are the AEM CAI , and an exhaust (RV6 duals).

FamilyGuy

The tune (flashpro) should be the very last thing you do.

StealthTL-S

I realize that, I may be done modding. My car runs great, sounds good, and I want to stop before I do something like hack the nice type S exhaust up.

Go through bit for tuning and flashpro. It's like 750 which is unheard of and the guy is legit (I'm on my 20th calibration from him)

FamilyGuy

Nice? The only thing nice about it are the tips IMO, and all the aftermarket exhaust options for us have nice tips too, depending on your taste. The factory exhaust is too quiet and has 3 mufflers, and at least the 2 mufflers at the tips are not a straight-through design. Get rid of it.

I was the same way with my S. Then I got an ATLP exhaust, and have never regretted it.
