So I am working with a machine shop to get my own line of custom exhaust made.


I have a few options and need to know what is more desirable:


CATBACK:

-Straight pipes and leave it cut at the end and you can add on any mufflers you want, or weld the stock ones back onto this exhaust to get a more free flowing cat back with stock look (Would be less money of course).

I will / can have these made in 2.5" piping or 3" piping for FI guys.

-Make a dual exhaust for both Base and TYPE-S, tips for the TYPE-S being a bit larger.

-Make a dual exhaust for TYPE-S and make a single tip for Base.



Anyone have any input on what option to go with, which one would be more desirable or any inputs on what tips one would want? Would you want to spend less and get any mufflers you want, or have it pre made? Remember one thing about pre-made stuff is that it doesn't always fit perfect as if it was built on the car (almost like a tune). Not to bash anyones products, but for instance, when you add on the A-spec kit it extends the bumper a little and if the muffler is welded on the car it can be pushed in more for a tucked in look or out to be flush with the kit. Also those who have the RONJON kit it they can have an exhaust made to fit flush/pushed in and so forth.

I will also say that pre-made exhausts are much easier and simple to just bolt right on and be done.


In the future I will have pre-cats and J pipe as well, but that is after cat-back.




If anyone has a TYPE-S exhaust I can borrow or buy who is local to NJ, let me know so I can bring it to the shop with my base exhaust and start getting dimensions / production ready.

 

would you have one with a resonator option? or a long catback to replace OEM caatback and OEM 3rd muffler?

I personally would like a 3" but that is because I am thinking turbo but a 2.5" is more than enough for even F/I needs and will be what the mass populace needs

if you add dual tips to the base it truly comes down to what it looks like
since the base has a square opening two round tips might not look good.. but until there are some pictures it is hard to answer

as for pre-made or just piping to mufflers.. I personally would like the piping to mufflers... that way I can figure out what mufflers, tips work for me

but you are right.. there is something to be had with a straight bolt on product

if you do a pre-made bolt on maybe have a one inch extender at the connecting pieces to extend for a-spec other body kits..

probably an inch think flange at the jpipe to straight pipe.. or another connecting piece since you are thinking of shipping this

 

First of all thumbs up for the idea !
What mufflers are you thinking of using ? what resonator ?
I think that 2.5 and with dual tips for both Type S and Base, with Base tips looking like 67$ tips.

 

In for dual straight pipes and cut at the ends...

 

anyway to do a single tipped dual exahust with a tip that compliments the square opening and lines of the bumper?? round tips in a square hole...just doesn't seem like it looks right.

i like the dual tips idea for the base bumper....BUT...they are so little compared to a type-s quad (b/c they are). to me it looks a little funny to try and cram so much into so little.

 

2.5" piping and pick your own mufflers would be awesome. A company used to make a kit like this for my previous car. Was like $200 and all you had to do was choose a muffler.

 

I have always been dumbfounded by all the exhaust options for the base tl having round tips which IMO makes absolutely no sense since every single body line is angles amd straight lines. Even the aspec bumper is shaped around the exhaust tips so if u could make an exhaust tip similar to the stock one except bigger so it fills in the opening and is a true polished tip and not just the "add on" like stock, I would be all over it!

 

Killer good idea buddy.....

i love the "customize" your own....i would suggest dont make things dedicated for the base of type S....leave the choice to the consumer....

have choices like:
1> 3" down pipe
2> 2.5" true dual down pipe
3> resonator cut out
4> provide some resonators/mufflers at a decent price

this way you will leave the choice to the consumer....make this a one stop shop and maximize efficiency

also have options like SS/Aluminized/etc piping....

hint: custom jpipe/PCD might sell well as well

 

let me know if you'd be interested in making parts for the 2G tsx as well, we have very very few options right now for our cars

im sure an axleback and a test pipe would have interest

 

anytime swoosh

 

damn son you got a great sense of humor

 

Yeah the company is KTeller. But last I checked they do nothing for the TL. But that's exactly what they do.

 

Actually the site I was referring to was Hogan Performance. They're a real small company that makes stuff for GM 3800 powered cars. http://www.hoganperformance.com/products1.htm

But I'm glad to hear they're not the only ones doing this idea!

 

I don't see the point in "Dual" exhaust-- even though, Richie has made a good product. It is all for the name/saying that you have one, but it does nothing that a single exhaust wouldn't (unless you're running over 700WHP). Single exhaust setup at 2.75" for the non-F/I crowd. Single 3" for the F/I crowd. Build the exhaust like the Comptech with the stock tips (or ATLP-type tips) but with a resonator (deeper sound). I have not heard one exhaust better than my Comptech + Aero Resonator yet.

 

^^^ hater

no but i like what a true dual can do....drive a car with a catback and then with true dual....it does give that extra ooomph....

yeah but piping size makes a lot of difference.....

 

^^not only a hater,straight annoying...needs to stay in his lane,never has nothing good to say


I would be interested in the first option....

 

^^^ hahah nah bro....he is a very knowledgeable dude.....we mess around all the time....

 

I've wondered about the dual exhaust myself...would the added weight of all that piping plus the overall pipe size be beneficial over the stock exhaust or a single 2.5 or 2.75 piping exhaust ? If im not mistaken I think one of the dual exhaust dynos for our cars actually showed a loss of torque?...

 

^^^ added weight is only for the small section....as you see there is a merge near the 3rd cat in most aftermarket jpipe....and a split couple feet down....

so the only added weight is for that couple feet....(am assuming 7ft)....so find out how much does 7-8ft of T304SS weight and that is your added weight

 

That hurts my feelings.

 

hmm.. dual exhaust would affect my TL diet.. oh well the car as myself or just fat asses

that said

piping up to the mufflers would be great, i would jump on that

 

When you said dual exhaust I didn't know we were talking about true duals. Just a single with a Y pipe at the back for dual mufflers would be fine with me...

 

I would be interested in the "add your own mufflers" option

 

I think we just hijacked the thread a little with true duals... Ack hasnt written anything since the beginning so not sure where this is going.. I think customers are there for this feature since it would truly making this like modding muscle cars!!!! well sexy muscle cars

 

I have been reading and I gathered that most would want the put your own mufflers option because some can just use this piping and have their stocks welded on for that stock look or find their own mufflers.

I am bringing the exhaust to the shop this week or next week to see what we can come up with. Some can even get those "bolt on tips" and run straight pipes without mufflers.

 

I love this idea!

 

Im in for this as well. Love where its going with the "choose your muffler" option

 

Bruce like I said this past weekend - I love this idea! I would want 2.25 to 2.5" piping and I'd add a 22" magnaflow resonator w/ magnaflow 14807 or 14816 mufflers...

 

I may do 2.5" but I got some solid measurements this week so we should come up with some good ideas. This won't be made by next week but I am pushing for the next few months and once I get the OK that it will be made and have the first one on hand, I will take deposits and more ideas. Then start with a J pipe.

 

Are square exhaust tips possible? I've actually never seen a seller on AZ make square tips for the 3G TL. Considering all the hard angles that the car has, square tips might be fashionable AND unique.

 

I also find it very difficult to find affordable angled dual tips. If someone started making these for about $100 each, they would make lots of cash moniesss
Love the idea of a custom exhaust. Saves money, gives owner more input

 

Here's my opinion.

We all want torque and we all want horsepower and we all want a quiet low rumbling sound. So how would we need all three of these to accommodate with each other? Easy.

TORQUE:
A well designed exhaust high performance street exhaust will be 2-5psi of backpressure vs 16-18psi of choking stock exhausts.

POWER:
Lots of companies have gone the straight-through design for maximum power. Most of the time, it's LOUD. many companies have built their systems to be farily quiet, such as FULL RACE as I had one on my Civic SI (3inch catch back).

Sound:
On straight-through mufflers, the longer the muffler and the bigger the can, the quieter it is. The length usually has no effect on backpressure, just noise output. So what does this mean to you?

I've have many exhausts from Tunabe, Skunk2, Vibrant, TenzoR, GReddy, HKS, etc. You know the names, and they all have different sounds.

I personally Love low sounding exhausts. It makes the car sound aggressive when it's stepped on, when the car starts, and when you shift to the next gear.

BUT I DONT LOVE RASP, FART CANNONS, or cheap materials.

A high-grade made exhaust will produce the right sound and will make everyone jump on it.

This has lots to do with your capability, your tools, and your designs.

Perforated core over louvered core - why? Because it makes the MOST POWER.

I've used many resonators in the past and I personally love the VIBRANTS brand as it tones the car down. others can use MagnaFlow and such.

With the TL's powerband, we will get the best sound from mid-range as our power comes alive there. With having many DualOverHeadCam engines, the noise on these can be loud as more power keeps picking up on those high RPM's... sadly, the TL wont.

My preference on the exhausts would be dual or dual tips or singls.

I don't know about you guys, but I love GTR's exhaust, how they look and how they are designed. If we can get that type of design on the TL, it would be flawless.








BUT, i'm a nutshell on exhaust and the sound... I still want to see a vendor yet do this.

 

^^^ i agree with you 90% of the post LOL....disagree a little on the sound part....

no matter how high grade material you use, RASP does not depend on that....RASP depends on tuning the exhaust frequencies...having the muffler/mid muffler/resonator at the right place....

other than that, your right on the money....my true dual exhaust is loud as a bish LOL....and has some rasp from the 3000-3500 rpm range, but i wanted the exhaust to be as free flowing as possible....i can add another mid muffler to tone down the sound but i really dont wanna mess with the flow LOL....

here is a cold start video and a rev video for reference:



the mufflers/design is in the thread in my sig...

 

My buddies have a BMW M3's and they experience rasp. A group by Custom Performance Innovations developed a pipe that eliminated rasp called the Rasp Terminator. This could well be a part that someone could make to bolt on to their exhaust systems or for people who dont want it can make a straight through exhaust for that section.

More people making parts for the TL means more parts available = compitition. Prices will drop. If only I can dream to that day.

 

Bouncer, I absolutely LOVED my 3" Full Race exhaust on my Si...if they could only make one for the TL, I'd buy that ish in a heartbeat...you're completely right, it was one of the (if not THE) quietest 3" out there...

 

Sorry guys I haven't had time to fully sit down and discuss ideas yet, as I have been doing 5 - 52" trailers with vinyl and that is taking a long time. I have been thinking of ideas though and I am pretty much set on just the piping and the customer gets their own mufflers.

 

^^^ Sounds good, how about having the option for a resonator in the midsection too? Any pricing options? I would definitely only be interested in 3" piping...are you offering that too?

 

Yeah I will be offering 2.5" and 3". Resonators and such I would probably have the customer do as well because there are so many kinds/styles and where to place it would be key as swoosh said. I myself had a 3" exhaust once with a 24" resonator that made the exhaust sound stock but screamed when WOT.

 

If you mean with resonator only and no additional mufflers, then you obviously did not have the PCD.

 

^^^ right lol, on my custom exhaust I had a 22" resonator on 3" and still had rasp so I said f it and took it off. Sounds better without it, yes its loud but I dont mind. But I think its still a great idea, with more research than I did im sure you can have a really nice setup.

this is after I took the resonator off. Make sure you watch the whole video its gets better at the end (last 20 secs) , sorry for poor quality
