getting jpipe installed tomorrow....after waiting 3 weeks because I was just too lazy....smh

post a video with before after sound if you can... at hte very least let us know what you think of the performance gains.. thanks.

Sniffles

I got a custom exhaust so I doubt the video will help you guys who have stock exhausts...I'll post it later on but I'll def give you my opinion on the performance

brinox

im definitely feeling the mid-range power increase when stepping on the gas... I do notice some slight increases in exhaust noise, but nothing compared to what I was expecting given the other assorted video uploads around.

Tony Torque

Definitely need this in my life!!!! Now has anyone looked into headers?

neuronbob

OK....to me you can't talk about increase in power without a dyno (e.g. objective information). If there is more noise it can SOUND more powerful. Sorry, I'm just a stickler for this when people pull out "seat of the pants" descriptors. Just my and I did this while I owned and modded my RL.

So has anyone done a before and after dyno of this setup? Not that there'd be much change from just a J-pipe, but if there is, someone oughta document it.

Ok so I just got this installed. I have not reset the ECU yet. Only had a chance to drive to the groceries. I also finally got my rear 09 sway installed at the same time. I think I feel more hp (even thought I think anything under 20hp can't really be felt right?) I did floor it to the groceries and back. It started to sprinkle, so I am waiting for it to go away before wasting more gas. I will reset ECU and drive it hard when I get a chance.

Weak! No dyno, just speculation at this point! Although I am glad this is available for us, it's weak, so many people bought and installed and all we get is it sounds good I feel and increase blah blah blah! Post some real results and quit making me waste my time to check this thread!

neuronbob

^^^^^
The point of the J-pipe mod is to make the exhaust tone deeper for those who like a little sport with their lux. That's pretty much it and there is certainly nothing wrong with that. It's really not much of a power adder. If you're not interested in a different exhaust tone, then you are indeed wasting your time. All the reports so far are positive, so it must be meeting the expectations of most.

That said, I'd love to see a dyno to document whether it indeed adds a few hp. If it happens, great, if not, equally great for the reason stated above.

Keep wasting your time bud.

Just wanted you to waste your time.

Let me know when you get one installed and post up real stats and not just dropping tears on your key board.

oo7spy

The 3G TL RV6 j-pipe has a proven gain of 13/7 whp/wtq peak & 15/12 whp/wtq average. (Although, it is impossible to have an average higher than the max.)

Where do you get this idea that a j-pipe is not performance oriented? IIRC, your exhaust/intake combo only produced a 12 whp gain. Could you not feel that?

253RL

Obviously changing part of the exhaust from anything other than stock will increase the tone, however that doesn't mean an increase is their, that said I do believe a less restrictive j pipe will produce results and is the probably the best performance mod for the RL. As for you mr Heavy... No tears here guy, just interested in some numbers as butt dynos have never proven to be reliable!

fatty

Ok, so just done resetting ECU and went for a spirited drive. And dammnnnn, either I've been driving like a grandma or I I can feel the difference!! I feel in the mid to upper rpms pull harder. I don't think I have reset my car even after the pulley and intake. But I do love the feeling!! Right after a reset, I noticed a change in tone in the exhaust outside. In the inside, I can't tell a difference. I am liking this mod!! I definitely recommend this. I originally based my purchase off of the TL dyno posted above. I probably will never go dyno my car. I also want to note, I do smell something now with the jpipe installed. Dunno if its because how hard I drove it or because its more free flowing, but the smell is definitely there.

ichi d

Fatty which method did you use to reset your ECU?

fatty

I turn ignition to number 2, stepped on the gas for 30 seconds, while keeping the foot on the gas turned the ignition off and then let go gas. Sat for 2 minutes and I think I heard a click inside the car after about 2 minutes. Then off I went!

neuronbob

Thanks for the data, oo7spy. I did say, "not much of a power adder". I guess I stand corrected on that front, and happily so. That much to the wheels should definitely provide a "seat of the pants" effect.

I'd love to see some RL data but expect less at the wheels because of the severe parasitic loss of SH-AWD, which I documented in my multiple dynos.

Rock on, all!

oo7spy

I would love to see a dyno or at least 0-60 compare as well, but Richie realizes the difficulties of the SH-AWD on a dyno just as you and Touge did. I think with the 3G TL data we can assume at least 10-11 whp based on a 15% loss in the TL and 30% loss in the RL. With ~220 whp in the RL, you would be looking at a 5% gain.


Is the 3G TL engine 3.2 or 3.5?

neuronbob

Both. The non-S TLs had a J32A3 engine and the Type S had a J35A8.

oo7spy

That's what I thought. I know the Dyno above was done on the base, so the 3.5L should gave better gains I would assume.

i just purchased the precat deletes a few days ago. waiting for it to come in we'll see if it fits..

should be a nice combo with the j pipe (still in box in garage)

will report back soon

EL19

iTrader: (4)

I believe they were already proven to fit. Do you have an exhaust mods? or are you going with pre cat deletes, jpipe, and stock cat back? Those two mods alone on my Accord's 3.5 yeiled me over 40whp and 40wtq. It was amazing the combo of only those two mods on stock catback

Sniffles

Which car would it work with ours? I forgot.

EL19

iTrader: (4)

3rd gen TL and 7th gen Accord Precats for pre 2.5 gen RLs (05-08). If 09+ its the 4th gen TL and 8th gen Accord pre cats

253RL

Let me get this straight.. The 3G tl and 7G accord precats work on the 2G RL?! Where can I found that info? If that's true then thats a hidden gem for sure and coupled with the j pipe should most definatley yield some WHP!

vletnguyen

iTrader: (1)

i ordered the 3g TL pre cat deletes. This with j pipe is still way cheaper then any brand name exhaust for our cars, might even yield more power also.

I have oem cat back. hopefully it turns out well ( it should)
I'm still waiting to get it in the mail.

fatty

Cool, let us know how it turns out!! I didnt know these fit either! More hp in the low end or high end you think?

253RL

Guys this is amazing! I can't wait to hear how the two sound in conjunction with the oem catback which I fully intend to keep! Unless of course the 5zigen becomes readily available! Man we definatley needed these mods to get some of our HP back that the AWD system stole from us, I can't say how excited I am. Anyone know when the next batch of j pipes will be produced? Or a list I can sign up for?

SSjTrunks112O

Approximately 2-4 months.. You can go to the RV6 website and be notified via email when the 3rd batch is good to go..

253RL

^^ awesome thank you sir!

SSjTrunks112O

Is there any difference between the high flow pre cats & pre cat deletes besides what's indicated on the RV6 website? Do the HFPC's provide higher whp & wtq gains when combined with the J-Pipe & Oem Catback? Is there any difference in sound or ability to pass an inspection? From what I read, they both seem to fit but the HFPC's are $200 more..

Also, what's up with the "Intended for off road use only" statement on the RV6 website? Does that apply to the ceramic coating only or the product itself?

Thanks in advance..

EL19

Jpipe gives you power in the low end and mid range, while the pre cats provide more power in the high end. But both of these mods provide power throughout the entire powerband. They are the two best mods for any j series engine (for older j series engines headers are)
The difference is the pre cat deletes are just straight pipe with no restriction and the high flow pre cats are 200 cell catalytic converters

HFPCs DO provide whp and wtq gains, even paired by themselves. the gains only climb as you free up more parts of the exhaust system (jpipe, and catback)

from what I've heard there is a SLIGHT difference in sound with HFPCs. With PCDs the sound is more noticeable and may create rasp on a non resonated system

I dont think people who do visual or sniffer inspection tests can pass with the PCDs but they should be able to pass with the HFPCs (i think)

The intended for off road use applies to the actual products because it is illegal to change catalytic converters if they are not damaged or to remove them altogether. Its a disclaimer. same as the surgeon general warnings on cigarettes and alcohol

Depending on what state you live in though there is no real risk. For instance I live in Maryland where if there is no CEL I pass emissions inspection. So i can run catless cars through there all day if there is no check engine light.

When I get this raise I'm expecting I'm going to order the PCds or the HFPCs. I'm really leaning towards the HFPCs

SSjTrunks112O

Thanks for the info. That would eliminate PCD's for me then since I'm trying to avoid the rasp. Do the HFPC's result in more rasp over Oem? Would it affect my manufacturers warranty? (I don't want the dealer to try or say something fishy) Lastly would it increase the chance of a code appearing. Thanks again!!

EL19

iTrader: (4)

No problem.

No codes should appear with the HFPCs, if they do something isnt connected right.

From the reviews I've read and videos I've seen with HFPCs, there is no rasp produced by them. They barely change the sound at all. Just makes it more aggressive.

Lastly, the manufacturer would have to prove that the part is what caused whatever you are trying to get fixed under warranty to fail. Check out the Magnusson-Moss Act. Typically, exhaust mods are overlooked as they really do not alter anything. But with changing the cats I would assume your emissions warranty would be voided. But I'd just chnage them back if you ever had a problem related to emissions (Doubt you would)

Tony Torque

Does anyone with PCDs have a CEL on for the O2's?

EL19

iTrader: (4)

No, not unless they installed the defoulers incorrectly

fatty

For the hfcd it says 200 cell, the higher the better or lower the better?

EL19

iTrader: (4)

The lower the cell count the better the flow and less restriction. I think our stock cats and 3rd gen TLS cats are 600 cell. Stock 3rd gen TL cats are 900 cell

253RL

Can anyone point me in the direction of those pcds fitting our 2g RL the mod bug has me itching and I'd like to know for sure before I dive in blind, my wheels were enough to get without weds telling me they fit 100%!

EL19

iTrader: (4)

Theres a thread out there and blazing GT had them I remember seeing. I have to find it.

But the 2g RL and 3G TLS motor are exactly the same. You'll find out soon for sure though through vletnguyen
