Go with the jpipe that has the fastest shipping. xlr8s got that 1 day shipping to NY

TLOHTL

wow. Im really shocked....actually im NOT.
Your putting a whole " Song & Dance " to try and cover up the FACT that your J-pipe is :

Actually losing power
- Poor Quality ( vs. ATLP & XLR8 )
- Super Raspy !

Ill say this AGAIN and hopefully for the last time. I Dont see ANY VENDOR doing a b4 / after dyno with there j-pipe on a TL that has PCD's. I have done a b4 / After , and I LOST POWER with your RV6 v3 j-pipe.
And as soon as I replaced it with the stock Crappy J-pipe/3rd cat I regained the power.
Unless someone wants to Dyno the following : 04-08 Base 6-spd TL with aem cai & pcds , then go and add a RV6 v3 jpipe and do some b4/after dynos... I would kindly appreciate silence

In all honesty I have delt with Xlr8 several times. And his level of customer service and quality of products is second to none.
So dont worry I wont be interested in any Further rv6 products!
Unless you really start improving on your quality and customer service. Now I dont mean to start a battle or go off topic so ill get back on topic....

OP go with the xlr8 v2 j-pipe or stay stock.

TLOHTL

Also id like to add the fact that I have also done a b4/after and a thread here on Azine : In regards to your PCD's. ( RICH RV6 )
And I must say your v3 PCD's so far seem to be the best single mod. ( in comparison to : aem cai , pulley, spacers, cat back and your rv6 v3 j-pipe )
I believe I gained about 16whp. Im sure you can find the thread.
But your J-pipe did NOT work well ( At least on my set-up ) .
And also I did NOT like the quality and I Did NOT LIKE THE RASP. And there are many members who will agree.

I felt an immediate difference on mine, but I didn't just change a j-pipe, I changed j-pipe + exhaust. I'm also manual and have light weight FW and pulley, so maybe that amplified the effect.

And yes, the RV6 j-pipe and exhaust that I received are VERY HIGH QUALITY materials, welds and construction. Same goes for XLR8.

6spd-GERCO

TLOHTL... tired of you bashing RV6's products. if you don't like them talk with your money and take your business else where.

I gained HP with the J-pipe... of course I am tuned but look at the graphs and tell me what you think. First dyno the only mod was the RV6 Exhaust. Second dyno I added the RV6 J-pipe and installed my noise maker.... my CAI and some tuning. VTEC is high.... I know, at that time it was an in progress E-tune.





Does this stuff look poor quality to you?

Small side question, 6spd-gerco, what's your vtec set at now from your tune?

On topic, I believe all three vendors put out amazing products and have great customer service. Both Richie and josh have answered my concerns on weekends and are willing to do what's necessary to make it right

pics or it didnt happen yo!

6spd-GERCO

VTEC window is 4700 rpm to 5000 rpm

TLOHTL

Thank you !
Like I said b4, many people who " FEEL " power do several mods at once.
Each mod should be done on an individual basis.

?? only 300 rpm range? am I reading this correctly?

TLOHTL

First of all I'm NOT bashing RV6.
I do NOT like the RV6 v3 j-pipe and would much rather keep the stock one.
I lost power with it ( on my set-up which had RV6 v3 PCD's , which I REALLY LIKE )
Also the build quality vs the competition is NOT up to par.
Lastly the amount of RASP when paired with PCD's and a HUGE resonator is unbelievable. It makes the TL sound like a ghetto lawnmower.

Now the Rv6 true dual is a NICE piece ive seen it in person and paired with the j-pipe sounds pretty good.

So you 6-spd Gerco made 230whp with just the true dual ?
Then made 250whp : rv6 v3 j-pipe, cold air intake and a tune ?
Search is your friend ... And I made if memory serves me right about 16whp with just an AEM cold air intake.
So I would say your increase of 20whp when you did rv6 v3 j-pipe , cold air intake and tune came from the cold air intake and tune.
Save the b.s. About how an AEM cold air intake doesn't add any power and it's a noise maker. I have about 2 pages of ppl saying that.... Yet funny thing is.... No one has done a b4 / after Dyno on a stock 6spd TL with the AEM Cai. ( except ME )

And I don't believe any1 has done a b4/after Dyno of the RV6 v3 j-pipe b4/after on a TL that had : Cai, and v3 PCD's.
So please if you want to comment and prove me wrong.... Please PLEASE do so , spend some time and Money and put your TL on the Dyno and do some individual b4/afters. I have with : AEM Cai, Rv6 v3 PCD's , rv6 v3 j-pipe, xlr8 v2 pulley, 2.5" cat back.....

This thread is really getting off topic. The original OP wanted to know which J-pipe to go with.
I have left my opinion, and why I believe what I post.

At the end of the day : you have a few options :

- leave your stock
- get a Rv6 v3
- atlp v2 or v2R
- xlr8 v1 / xlr8 v2.
- build a custom j-pipe ( hats off to you ... SERIOUSLY ! )

Again my opinion based on build quality/design is XLR8 v2.
I'll have results up shortly on how it performs

TLOHTL

I Think 6-spd Gerco doesn't " know " when his vtec engages.....

He's saying appx 4,700-5,000RPM....

iTrader: (5)

I was confused by this too haha

6spd-GERCO

I think that's your problem (2.5" catback) You've opened up the first portion of the exhaust and now need to open the rest of the exhaust system to help your flow. Look at which direction ATLP is headed... 3" collector for the J-pipe to 3" all the way to the y-split for the mufflers....Can you show me a video of said ghetto lawnmower lol i didn't know there was a difference.

Glad to hear your not bashing RV6 products......


Oh you know when VTEC engages on my TL now!

Yes, you read it correctly.

How are you guys confused? VTEC window rpm is what I am looking at. VTEC window allows the VTEC point to move higher with a lighter engine load. If I floor the thing or my MAP is above .85 bar, it's 4700 rpm. If I am below .85 bar it's 5000 rpm.

FamilyGuy

You missed my point. Some mods, like individual pieces of a system, such as our exhaust, will be affected by the rest of the system. Testing each mod on an individual basis doesn't tell you the end result of the system as a whole. In this regard, testing each individual item is useless, because the rest of the system can have significant effects on each part's performance. If you want to measure a parts performance overall, you need many tests, one for each system configuration, which you haven't done. All you did is one single test on one single config.

Also, I believe it's been shown here on Azine that PCDs add rasp to both rv6 and xlr8 j-pipe / exhaust, maybe even the OEM j-pipe and exhaust too, I forget, so why you only saying rv6? Don't hate, appreciate. And take an anger management class.

if stock air box flows just as well as aem intake, where did your gains come from?

<---currently building a high flowing engine that outperforms OHTLOH stock engine and Im still using the stock air box.

Uh oh. An intake debate inside a jpipe thread. Shit just got real.

Was bored so found his dynos. Only thing I noticed is STD smoothing was the same for all runs except rv6 jpipe vs stock runs. :shrugs:

I wish an aem intake would gain 16whp...because then my custom 4" would gain even more

iTrader: (2)

?? Eh? I didn't say I could feel a difference between any jpipe, I said I chose based on results, and also as you point out, on service/price. Richie was quick with the responses and I got a great product for a great price, and no regrets. The "results" I was referring to are in the video below, which helped me decide. Plus I don't have an AT, so...

^didnt mean to call you a liar. lol

right, as we are experimenting with each car on our own, we have our own ideas on what makes power.
and that's the best we can do, since lots of variables can skew a dyno, so we cant hold that much weight into it.

Also, the cool thing about Richie's jpipe is that he can modify it to be an actual X over, couple this with the rv6 true dual exhaust and its a beast!!

6MT for the motherfucking winn!!

6spd-GERCO

I made good gains, more than I was expecting on my TL with the addition of the RV6 J-pipe and tune. It's an Injen CAI btw...Installed it and and then switched back to stock for a while and now it's installed again. A large chunk.. most...of those gains from my first dyno to the second dyno came from the RV6 J-pipe and the tune. To say that most of my gains came from the CAI is funny... If I put the stock air box and make the same HP what will you say then?

And with FlashPro I would be able to tell you if the IAT was closer to ambient for the stock air box vs the Injen CAI (on the street). The dyno and real world are two entirely different beasts!

Just to put this out here. If you want back to back dyno numbers I will get them for you. Just send me $30 for every test you want. I have a set of rv6 pcd and a v3 j pipe. The car is a 04 6mt currently only mod is aem v2 intake, type s intake manidold, and 3.7 tb. I will provide results and videos for rv6 atlp or the stock stuff. I will not touch xlr8 stuff. Their customer service is horrible and the products are worse than the service.

TLOHTL

Yea .... Ok .....
Xlr8 has awesome customer service and QUALITY PRODUCTS.

And we don't need you " putting it out there " .
