Hi,

I've done a fair bit of research and the RV6 j-pipe, true dual catback, and HFPC work together to create an orgy of orgasmic eargasms that brings all the panty-dropping chicks together.


A couple of questions for the pros out there...

1. How much will that set-up cost (that is if I do get the combo, seeing how the true dual exhausts are currently halted)?

2. How long will it take a decent mechanic to get all those parts installed?

3. Is there a specific order that the parts need to go together. I ask this because I don't know about getting the HFPC, but I would like to have the option of adding it in in the future if I want to.

4. What exactly is a high flow pre-cat? How does it differ from a standard precat delete and will it still pass the strict emission laws? Can someone show me a numerical comparison of the emissions of a having a HFPC/PCD with RV6 j-pipe when compared with a stock on a 2007 TL Type-S ?

Off topic question 5. Anyone know where I can buy a rear window spoiler?


Thanks for any and all answers, I really learn so much from you guys about cars its crazy. Much appreciated!

kleenc2000

Blah, two more questions...

5. Does the j-pipe connect directly to the cutback exhaust, or is there a segment of piping in between?

6. Does installing the exhaust pipes mean cutting and welding is necessary, or is it a simple bolt, screw, and glue effort?

1-check prices on rv6 website...or email him (ritchie) for possible combo discounts.
2 and 6-you can DIY and save yourself some $$$. it is all plug n play. no welding, no cutting, no glue. time wise...1-2 hours assuming you aren't fighting the car with rusty bolts and you have and extra set of hands with some airtools.
3- you can add/swap parts of the exhaust as you go along. some start with the j-pipe, then PCDs/HFPC then catback. some start with the catback then j pipe and pcds/hfpc. depends on how much you want to spend at a time.
4- someone else can chime in on the specifics of the difference. all i know is the pCDs will do what they say. delete your 1st and 2nd catalytic convertors and thrrow a CEL since they have sensors to your car's computer....ie...no pass emissions/FAIL...hi flow i would assume (as it says) improve the exhaust flow from the engine to the rest of the exhaust to allow the car to "breathe better" without completely deleting the first two catalytic convertors (ergo, no CEL), but your emissions will be slightly higher than stock, but not enough to fail emissions standards. PCDs also will give off a bad smell whereas HFPC will not.
5-ebay, blackmarket
5a-there are many threads that discuss this...
simply put: engine, cats, j-pipe, to catback. rv6 and xlr8 jpipe will delete the 3rd cat and will not throw a CEL (no sensor, so car will not know its gone). maybe a few more exhaust gurus can give you more detail as to the entire breakdown of the exhaust system...i have given you the simplified version of it (you know if you run a search you can find this info too, just sayin' ).

kleenc2000

Thank you so much.


As for 5a, I was just wondering because it would be kind of funky if two new pipes (j-pipe and catback) were connected by a rusty straight or something, but I guess that is not the case, unless someone else states otherwise.

Thanks again!

everything is bolt on.

like I explained earlier, you can buy one part of the exhaust at a time, and it doesnt matter which peice it is.

some just do PCD's.
SOme just do catback.
some just do jpipe.

or any combination of the 3.

I started off with just jpipe.
then wanted more power and moved to the pcd's. I will buy the TD exhaust when it comes out.

everything is bolt on.
meaning, you uninstall stock part and bolt on aftermarket part.
SINCE, you're buying all RV6 products, Richie has made it where everything lines up and should not be a problem. the true dual exhaust is a perfect example of this. the x pipe lines up DIRECTLY with the jpipe.


stock primary cats have a 900 cell count.
HIGH flow cats have a cell count of 200 or 300.
PCD's are straight pipe. = no cat. or 0 cell count

the fenda rolla

Couple things, the PCDs come with defoulers (angled tubes that the O2 sensors screw into so the CEL is NOT thrown...). I currently have had these for over a month with over 1000 miles and still no CEL...

Also, the "smell" is not bad at all and most of the time I seriously cannot even smell it...

AbyssPearlTL

I love the smell.

newfrito11

without discussing price, does PCD or J-pipe give potentially more gains? are you wasting money by getting PCDs without J-pipe?

justnspace

iTrader: (1)

pcds provide more gains. but comes with drawbacks. smell, and rasp are common.

like previously mentioned, you can get any combination..pcds jpipe whatever your fancy.
it doesnt matter.

type-s'er

RV6 claims on their website 20 whp increase on an otherwise stock automatic base TL with their "true dual" exhaust. Is this true/possible? making me think twice about the ATLP quads i have lol

1st you didnt do your research....IT WILL NOT BE A TRUE DUAL....

this is how i would suggest you to go about it:
1> full custom:
Get the PCD's (hello rasp) or get the HFC's (tad bit less gains but hey ur legal )
Get a true dual from there....check my thread below for more info.....also look into this thread:
https://acurazine.com/forums/3g-tl-performance-parts-modifications-112/going-custom-exhaust-all-way-need-help-754624/

it will give you couple more options....and let you know about the resonator sizes and stuff....

2> semi custom
PCD's or HFC's
Rv6 Jpipe
single resonator
soft Y split
muffler + tips

pop a bear and Call it a day....

NO CATBACK will give you 20whp....without supporting intake side mods...

I just received an email from Rodney (JnR Turbo guy) with the dyno graphs of a base 5AT with exhaust mods and it gained 14WHP from Jpipe/3 Cat Delete/Greddy Exhaust on STOCK ECU....

Every catback is pretty much the same (XLR8/ATLP/RV6) and the gains will be between 2-3 whp TOPSSSS

cant really post the graphs yet....once i get a green light from Rodney, will post it up....

^idunno.
I'm expecting at least 10hp to get me at 250hp.
which would be consistent with other ppl that have my same exact mods.

I will dyno, as soon as i get a catback. on the same dyno, as my previous one.

iTrader: (5)

^^^ check ur email....gmail....

again the guy was on stock cats....i would assume huge gains is that guy had PCD's (since the source is all choked up)

iTrader: (1)

^as soon as I get it, I'll jump on the dyno!!!!

swoosh

iTrader: (5)

me too....dyno right now (fully bolted on) and then dyno with ECU /offtopic

kleenc2000

single resonator
soft Y split
muffler + tips
test pipes

The HELL are these?

swoosh

iTrader: (5)

LOL you did read my other post in this thread right ?

tl.acurazine.com/forums/showthread.php?t=839752&page=2

if you honestly dont know what they mean i would suggest getting a already manufactured exhaust rather than a custom one....

but here let me try to explain:



ignore the intake part for now....

1> Single resonator: Tones down your exhaust....makes it mellow....the longer the resonator the quieter the exhaust....if the resonator is toooo long then your going to hurt your performance....

2> Soft Y split: not in the picture....imagine 1 pipe splitting into 2 pipes....you need a Y split....the exhaust losses power from merges and splits....a soft Y split, is longer than a regular Y split and splits off with an easy angle hence not hurting the performance too much.....you can avoid this by having a single exit exhaust.....

3> Muffler + tips: Mufflers make your exhaust further quiet....tips are for show (and to a point sound).....

4> Test pipe: A piece of pipe that replaces your rear cat....its a straight pipe....

Let me know if you need more info

^^^ you bet....

kleenc2000

Wait so in the end, does helping the car breathe better by swapping out the restrictive pipes INCREASE or DECREASE mpg?

From a zero-knowledge standpoint, it appears to be two-sided, as the idea of making the car flow better should make it more (fuel) efficient, yet increasing average power on any car should decrease it.

Just wondering...

swoosh

iTrader: (5)

^^^ increases if you can stay off the gas LOL....

Again, your not increasing power....you opening the restrictions....you increase the power by pumping more AIR and more fuel....but since you clear up the restrictions and the O2 sensors sense that, the ECU modifies the AFR and hence you might see a little loss in mpg....

justnspace

iTrader: (1)

By GOLLY, you've got it!

kleenc2000

Yeah because I'm currently running 16mpg according to the trip computer, which is like 3mpg lower than the estimated city mpg, and my car (2007 TL-S) is pretty much bone stock as of now, so I wouldn't want to get it even lower with new pipes and stuff...

I drive mostly local in downtown LA, it's not my fault!!!

swoosh

iTrader: (5)

^^^ I get around 20 all city driving and 30-ish all highway....i do 60-40 highway-city so i end up with like 26mpg per tank

you will just need to try and shift early and keep ur foot off the gas with the exhaust....since the exhaust makes the passage clear, it does tend to suck up your gas mileage but 1-2mpg's with similar driving habits...

Hammer5312

You need some back pressure in the system, just don't want too much...otherwise you'll be scavenging too much incoming charge.

You're around the Dtla area ? So am I. What color is your car ? It would be nice meeting a fellow tl-s owner. I can also point you to the rite direction in mods

Rev_Hi

iTrader: (2)

How much louder would you say the 14WHP setup is vs stock. On a scale of 1 (stock) to 10 (jumbo jet loud)... I am just trying to get a feel if this setup will be too loud.

swoosh

iTrader: (5)

Depends what component you change:

Change to PCD's: There will be rasp between 3.5-4.5K rpm. You Gain about 20-ish hp
Change the Jpipe: There will be almost no sound difference. You gain about 15-ish hp
Change the Exhaust: Depending on the exhaust it will be different sound but it wont be loud at all (depending you get a nice setup and not a fart can setup like i got LOL)
