Suggest you guys jump on these RV6 parts, they're rarely on sale and they're the best in the business. I've had my jpipe since 2011, on my palladium 4G and now on my CBP 4G, still looks mint and working as intended. Had my PCD for years as well.

carbonTSEX

Gonna be ordering my precat deletes. Wanna get the ktuner too but not sure if I can pull both this month. Next month for sure. $25 savings does help but not gonna kill me.

Question: Do the studs use the factory jpipe nuts or are they reverse threaded like the factory jpipe studs?

HeartTLs

OEM hardware works. You're also provided with new hardware.

carbonTSEX

Placed my order.

I'm on the edge for PCD vs HFC. I personally don't mind the smell much but I don't want rasp at all - I've got an inkling the PCD is going to cause some raspiness.

Richie v6

The studs are same thread as factory. The studs are threaded at both ends with normal right hand threads.

I've had both. This was 09' with XLR8 catback, RV6 long jpipe and HFPC's; , sounds pretty sweet. I installed the mods in this order due to availability, catback, jpipe and then HFPC. The catback in my opinion was the biggest culprit causing the loud exhaust, adding the Jpipe and HFPC made the sound deeper and marginally louder. I don't know what percent would I attribute to loving/hating having a full exhaust other than it got me a lot of negative attention from law enforcement and idiots that thought I wanted to street race. It also gave me a lot grins when driving in tunnels and elevated subways stations, from fellow enthusiasts and friends. That said the drone was very obnoxious and ultimately I sold the catback since it was what caused it.

Now I run PCD and long jpipe, for maximum gains; our stock exhaust (AWD) is already very free flowing and I get the benefit of an aggressive exhaust note when I step on the gas and discreetness when I don't. If you already have a catback I'd go HFPC, if you don't get PCD .

TeamAcura

Stock AWD exhaust is not mandrel bent like the aftermarket catbacks and diameter is also smaller. I'm really thinking about those PCDs but my car is loud enough as it is. And I'm scared of emissions.

carbonTSEX

Im running XLR8 V2 jpipe, ATLP catback and CT icebox. Luckily my emissions aren't visual inspections so I'm good. Definitely gonna get the max potential. Exhaust is already loud when pushed so it's not gonna kill me if it's a little louder.

Ktuner end user kit will be my next mod with street tune done by Vit. Should be a fun drive down and back from Seattle to Portland area.

Nice!

Right now everything exhaust is stock, XLR8 round tips look the best (IMO) so to free up some power the RV6 J-Pipe and then the HFPC or PCD would be first step and then see how the exhaust sounds. Absolute last thing I want is drone on the daily driver - I've got the S2000 for that.

PCD and RV6 Jpipe, you'll thank me.

CruzanTLSH-AWD

HFC and J-PIPE for me.. Ain't trying to smell bad when i'm gunning.

Lex80

Is there a J pipe option for the fwd TL?

HeartTLs

iTrader: (5)

Not from RV6. I believe you're only FWD jpipe option is from ATLP.

Damir1987

I was wondering if this setup would cause any rattling/swish noise in the car? I've read some stuff on here about how just doing the PCD and long jpipe (3rd cat delete) causes some noise issues.

If it does, what would be the solution? Adding a resonator?

carbonTSEX

J pipe can cause vibration on the sub frame brace. You can space it out with washers to eliminate it.

HeartTLs

iTrader: (5)

I don't get any vibrations that I know of, but everything from the engine bay is very audible at WOT. Which imo sounds great.

Damir1987

HeartTLs - so you have the PCD and (3rd catdelete) Vjpipe correct?


Did you have to do any other modification to your stock exhaust to make sure you don't get the rasple noise that others have been complaining about when they do this setup? The noise is not so much vibration but rather a noise coming from the exhaust system itself.

carbonTSEX

You're fine with the factory exhaust. Rasp comes with the people running aftermarket exhaust and that combo.

HeartTLs

iTrader: (5)

No other modifications to it and yes, that's the setup I run. I definitely have some rasp but it's not excessive or obnoxious (subjective), and doesn't sound like a low displacement engine running no cats type of rasp. It sounds like a an animal snarling.

suspekt360

This is great to hear.
I have been waiting to hear someone confirm my suspicion that PCD + Long J Pipe + Stock Cat Back sounds good.

I'm going to call Ritchie to work out a PCD and K-Tuner combo order. Hopefully he can provide a package price since our Canadian $ exchange rate is at a 10 year low these days.... it's a 40% premium

I'm already running CT-E and Long J Pipe.

I spoke to turbogixxer so the etune route will be followed once the parts are in.

I will update the group once I've made some progress. It will be a few weeks before I start.

HeartTLs

iTrader: (5)

It sounds great imo. I would highly recommend to anyone considering a catback for the sound to first try running PCD+long jpipe combo. You'll have awesome sounding exhaust when you step on it, subtle when you don't. Plus the benefit of a lot more hp gain over just a catback, for the same or a lot less $, depending which catback you get.

CruzanTLSH-AWD

The smell of the PCD is my main concern to be honest.

CruzanTLSH-AWD

And the Rasp

suspekt360

The PCD has been ordered from RV6.
I will update the group once its installed with some impressions. Very curious to see how the "snarling animal" sounds :-)

Setup will be:
CT Icebox -> PCD -> XLR8 Long J Pipe -> Stock Catback.

After a few months, I will get K Tuner and E-tune from Turbogixxer.

Also leaning towards getting the light-weight crank pulley from XLR8 as ive only had good experiences with pulleys on my other J motor cars.

That's awesome. Keep us posted.

I have had nothing but impeccable customer service with RV6 Performance. Rich is friendly, extremely helpful, and responsive with any questions and concerns. They're highly recommended. I purchased the v2 J pipe about 6 months ago. Quality build is top notch and the install went smoothly. Took me about 2 hours on ramps, taking my time. Just got my HFPCs a week ago which will get installed soon.

suspekt360

The RV6 PCD set is in!!
I will write a review soon once I've digested the change.

My setup is:
CT Icebox -> PCD -> XLR8 Long J Pipe -> Stock Cat Back

The difference is noticeable. The car revs up harder, spins to
7,000 (seems like 7,200) much easier, and gear changes seem quicker with more immediate pickup after the shift at part throttle.

There is rasp but it's very different. I can't desribe the sound but will do so once I've driven more. The Rev matched down shifts are definitely more satisfying.... they occur quicker and the sounds are nice and mean.

Also, there is no resonance that I've noticed yet. No CEL yet either.

I will post a follow up soon.

carbonTSEX

Nice congrats. You get them in yourself?

suspekt360

Question for the experts:

Will reinstalling stock j pipe reduce fuel smell and rasp? Also, many suspect the power loss of going back to stock j pipe with pcd is minimal.

The pcd mod is definitely fun with more top end but im not loving the fuel smell or rasp. My setup is: icebox, pcd, xlr8 long j pipe, stock cat back.

carbonTSEX

After hearing that and knowing I have ATLP exhaust I may have to swap to high flow pre cats now. It'll keep the rasp and smell down compared to the deletes correct? I don't mind the loudness as I like how it currently sounds with the xlr8v2 J pipe and ATLP exhaust.

suspekt360

It's all subjective. I believe my previous setup with cte and XLR8 v2 j pipe sounded nice and subtle. Some say the j pipe alone doesn't affect exhaust note but I strongly disagree. Accelerating next to a wall/barrier always put a smile on my face.

I am going to put stock j pipe on and provide commentary.

It's also possible that the car running so rich is magnifying the fuel smell.....

I would love to hack into the j pipe and install a borla xr1 resonator but I'm done with touching my exhaust components ... I prefer the flexibility of bolt on mods only.

Can anyone comment if 3rd cat tames fuel odour?

Also, not to knock the j pipe at all, but I think the thin walls amplify raspiness under the car. A stock j pipe may quell most of my concerns.

KarKraze

I am no expert but just sharing my thoughts from experience........ without the Catalytic Converters all the unburned gases are passing freely through the exhaust, nothing is being neutralized or converted to less harmful pollutants, hence all the smell. Putting back the stock J Pipe may remove some of the rasp but the third Cat will not help much with the smell.
The fact that the 3rd Cat is not monitored tells me that it is not going to be close as effective as the main Cat. I also believe that the 3rd Cat is only there to make our cars qualify for the ULEV status.

What you are experiencing and dislike is the main reason I always recommend and suggest the HFPC before PCD's. I believe that the HFPC's has a 200 cell count which is just enough to burn, neutralize and oxidize the unburned fuel going through the system.

carbonTSEX

Yes I understand it's subjective I have the exact same set up as you with the addition of the ATLP catback. Those two mods alone do sound great and the gains are decent.

CruzanTLSH-AWD

Putting on the stock J-pipe will reduce everything 25% or so. The smell will still be there but not as strong. But it's worth the try. Borla round mufflers is what your talking about as a resonator?

"The 3.5-liter engine has 900-cell/in2 converters, while the 3.7-liter engine has 600-cell/in2 converters. "

"To ensure optimum flow and low backpressure, a hydroformed two-into-one collector connects the close-coupled catalytic converters to the main 350-cell under-floor catalytic converter."

I myself was thinking about doing the PCD with the stock J-Pipe but some of the Accord and 3G guys said the smell and rasp is still there but not really as loud as it was. But they also stated they got more power as well "3.5 guys" with the PCD and stock J-Pipe.

So you might be the first 3.7 Guy to give an update about it. PCD and Stock J pipe.

suspekt360

Thanks.
I am definitely going to try the stock j pipe and will report back.

CruzanTLSH-AWD

Sounds good.

Performance wise you should address bottle necks in order, else your exhaust performs like a coke bottle.

CruzanTLSH-AWD

Elaborate

suspekt360

Some more impressions before I put on the stock J Pipe.

1. The exhaust is growing on me. At anything below 3/4 throttle, there isn't really any rasp. It's only when you go WOT all the way that you get a distinctive kinda rasp from the tail pipes.

2. There is a separate type of whoosh that emanates from the j pipe itself. Its not really that noticeable unless you are very concerned with OEM style silence. It is most noticeable at part throttle tip in.


Now for some positive thoughts. Even more so for 2009-2011 5 speed autos that can rev match down to 1st gear (or those lucky 6 speed m/t owners)

1. Rapidly decelerating and downshifting sounds amazing. With the PCD, the motor revs up so freely that the throttle blips are just crisper, faster, and accompanied by a very angry j motor revving up freely.

2. Coming out of a slow turn down shifted all the way into 1st, the car "feels" like it pulls right to redline very quickly and the gear change to 2nd is immediate with strong acceleration after the shift.

3. There is no doubt that over 5,000rpm, the engine feels livelier, smoother, and shifts seemed to be followed by more power in the next gear.

Overall, it is very interesting exhaust setup that is maniacal when you lay into it but quiet if you don't. At part throttle, between 2,500-3,500, there is a baritone sound similar to a 350z.

Keep in mind, I still haven't done the K Tuner which is next. Very eager to get the full potential from this setup.

Will the car fully tuned, make more power with the stock j pipe or the aftermarket j pipe?

I really wonderful about overall volumetric efficiency of the PCD with long j pipe or PCD with stock J pipe. It could be possible that the stock j pipe paired with pcd provides better flow than PCD with the long j pipe.

One thing is for certain, the way the PCD uncorked the sound and intensity of the motor is rather addictive. It just feels that much more fun running up and down the gears.... especially getting down into a rev matched 1st gear and clawing out of slow turns with shawd in full power oversteer with t/c off... bliss...
