I wouldnt say I am confused but I just need some help deciding which route to go with

I have a comptech exhaust on my 06 TL as we speak and need to come up with a combo to

1) Compliment the exhaust.
2) keep the noise/drown in check.
3) have a reliable set up.


Possible combination

1) Richie's pre-cat deletes + Richie's J-pipe + race pipe
2) Richie's pre-cat deletes + Richie's J-pipe + resonated race pipe.
3) Richie's pre-cat deletes + Richie's J-pipe + J shift hi flow cat.
4) Richie's pre-cat deletes + ATLP J-pipe + ATLP test pipe
5) Richie's pre-cat deletes + ATLP J-pipe + ATLP hi flow cat


I am sure I am missing one or two combinations up there but I'd appreciate if people with experience with either of the above combos can chime in with their 2 cents.

I am thinking of going with combo 5, thoughts/comments?

Depends if you have any issues running catless.

I vote for #1 or #3

Is cost an issue? Because I see an option thats gonna run you about $1000!

BTW, I have a CT exhaust right now with the RV6 J and res test pipe. I should have the precat deletes and the non-res race pipe installed by the end of the week. My personal opinion is that the CT exhaust is too soft. You don't really hear it and when you finally get on the gas, my CAI kicks in and thats all I hear.

NA - 5
FI - 4

EDIT: it's really annoying not being able to use caps when appropriate .

EDIT 2: finally got it to work...PITA, though.

I am use to the greddy Evo since that is what I use to have on my 02 TL-S, comptech is too quiet for my taste as well but I am sure once I install the J pipe etc it would be a tad louder.

As far as going cat less goes, do any of you guys have any issue with the check engine light going off after going cat less?

I think I should have added another option, pre cat deletes+ATLP J pipe + resonated cat.

Jm, would you be selling your resonated race pipe? Also, why are you switching over?

jmkiang

iTrader: (5)

^ I am going to see if the non-res race pipe will make my exhaust note louder. Not sure about my res test pipe. I'll let you know about that.

Personally, I don't feel like the "extra" couple whp produced from the ATLP stuff (from what I've read) is worth the jacked up prices.... but if you have money to burn, jump on the band wagon.

NedShneebly

Personally, I'd rather blow $800 on the pre-cat/J-pipe combo than an aftermarket exhaust. I guess I'm a minority in the fact that I like the stock tips, though. The gains are close but you can install yourself, if willing and able.

Why not get both?

type-s09

i wouldnt do the cat deletes if you are n/a...i would only do it if you are boosted or spraying...both are good products

Option 5 ftw

iTrader: (1)

Well since I have run pretty much over half ur choices I would say option 1

I ran the atlp jpipe and I am currently running the r-v6 jpipe, my quick review of both is that there is no difference in power, they work the same way, don't get caught up by what biased owners of atlp say or by what r-v6 owners have to say

Atlp jpipe hangs bellow the subframe, so if you live in crappy roads, caution, the weld and bends are perfect, it is mig welded and painted gray, 2.25 to 2.5

R-v6 jpipe does not overlap so ground clearance is more than enough, the bends are perfect and it is tig welded, polished to a mirror finish, 2.25 to 2.5

Additionally
Atlp hiflowing 3rd cat vs r-v6 hiflwing third cat, will not rid the smell, and actually may create some cabin drone

Atlp racepipe vs r-v6 racepipe vs r-v6 resonanted test pipe, main difference here is price between the racepipes, ultimately its 2 flanges and a straight pipe, as for the resonated test pipe its got a tiny bit of sound deadening material which takes care of unwanted rasp

Atlp jpipe $400
Atlp racepipe $125
Atlp 3rd cat $350
R-v6 jpipe $350
R-v6 precat deletes $250
R-v6 racepipe $65
R-v6 test pipe $75
R-v6 3rd cat $250

I wish i could find an aftermarket j-pipe with atlp bends and richies materials/finish.

Where you get those prices?

RV6 j-pipe and race/test pipe together are both $360 shipped broham.

OTSB708

Only with the group buy the price is $360 for the J-Pipe/Test Pipe combo from R-V6 shipped

Separate they are those prices that Al put up..

Correcto prices are from acuratlparts.com and rv6-performance.com respectfully

Be patient. RV6 just became a vendor so I foresee a GB!

Richies Pre-Cats are the absolute greatest invention for the 3G..

but i personally, love the ATLP J-pipe... and with a comptech exhaust (wonder where ya got that from ) its gonna sound good... b/c the c/t exhaust at least has a mid muffler, which will REALLY reduce the droning effect more than any type of resonator will.. you may still be a tad raspy.. but i think its the perfect setup...i would LOVE a comptech exhaust for my car

^you keep saying that you're gonna want me to get those precat deletes lol

stillhere153

iTrader: (1)

it is because the precat deletes are the highest dollar per hp mod


AND YES RICHIE IS A VENDOR I FORSEE A BIG OL GROUP BUY ALSO

NedShneebly

They're $250 and repeatedly stated as best hp/dollar mod. Aside from the installation pain, these are the best mod for all the affordable bolt-on fans - boosted or N/A.

No point in getting the hi-flow cat, race pipe AND the test pipe since they are all installed where your stock 3rd cat is. Just pick one

ifirahse

iTrader: (6)

^ Yeah the hi-flow cat is an actual catalytic converter, the race pipe is a simple piece of straight pipe, and the test pipe is a resonated straight pipe. All go in the same spot.

lets get some pics in here

1) Richie's pre-cat deletes + Richie's J-pipe + race pipe




2) Richie's pre-cat deletes + Richie's J-pipe + resonated test pipe.





3) Richie's pre-cat deletes + Richie's J-pipe + J shift hi flow cat.




4) Richie's pre-cat deletes + ATLP J-pipe + ATLP race pipe





5) Richie's pre-cat deletes + ATLP J-pipe + ATLP hi flow cat

^ Nice post

nokiaboy808

which j-pipe gives better HP? the atlp or richies?

ifirahse

iTrader: (6)

^ Some people will say one, others will say the other.

In essence the difference isn't anything that's noticeable at all.

stillhere153

iTrader: (1)

Looks like you haven't been reading

The gains are identical, I'd be hard pressed to see a comparison dyno to proove me wrong

I had both as stated before, no difference

I can do a before after dyno if you want to pay for it

Thanks for all the comments and suggestions guys, I am sure this thread will help people in future as well.

One last question, would running cat less throw check engine light?

I have made my decision to go with Richie's pre-cat deletes + ATLP J pipe + ATLP race pipe.

nokiaboy808

oic... so it pretty much comes down to the quality and pricing between the two j pipes

JnC

iTrader: (12)

^^ Pretty much, I chose ATLP due to the design and also the fact that next summer I plan on installing ATLP quad exhaust and type S lip.

stillhere153

iTrader: (1)

^ makes sense although the fresh batch of r-v6 pipes looks very promising from what I've heard, the flanges have been revamped

Sonnick

I haven't seen the ATLP Jpipe in person but from the pictures it looks great.

I can personally speak for Richie's Jpipe as it's on my car and performing great. Definite increase across the powerband, with the emphasis on low end (1500-3000). However, each gear pulls harder and I love it. I just need an exhaust now to compliment the Jpipe/test pipe.

jmkiang

iTrader: (5)

I don't understand how many people quantify one product being "better" than the other. Aside from a few dyno runs (that all seem to have enough error in the results to negate the differences), there isn't much out there. I don't think anyone has measured the J pipes to see if the Y portions are EXACTLY the same length. Or if the ID of the pipes is 100% burr-free and/or smooth. Have the fabricators fatigue tested it and posted resulted? Or if the metallurgy will hold up to the elements.

I'm just saying... I know... I bitch a lot

Both products do the same thing. It should just come down to brand loyalty, cost, preference and prior experiences with the company (ATLP, RV6, XLR8). I know all of them (Mike, Richie, Josh) have excellent customer service.

Sorry, this Rockstar is making me crazy.

JnC, whatever route you take, you'll be happy and better off than stock.
