Hello all,

I know the j-pipe has been talked to death and yes, I did a prior search on said subject. But I still want some educated opinions if possible please.

I love my Type S and at first considered a ton of modifications, but budget and overall aesthetics have convinced me to keep it mostly stock if possible. So a CAI or short ram intake is out, some folks on here told me the stock one was made very well by Acura. Replacing the stock exhaust system is out because damn, I've wanted this dual DUAL setup for a long time. It's just too pretty.

I currently don't want to do a pre cat delete. I'm not sure if I want to do even a 3rd cat delete. This leaves me with the only performance upgrade possibility of a j-pipe.

Let me explain. My Type S is auto. I use it as my daily driver to work. Unfortunately my work is nowhere near a freeway so I end up having to drive 9 or so miles each way in CITY traffic. All I'm looking for is to maintain power in the low end (much stop & go), gain a few hp, gain some overall performance, and hopefully gain a mile or 2 per gallon of gas. I don't need a rasp or a drone in my exhaust note, so the closer to quiet the better.

I've been reading and thinking of a j-pipe change to help open things up. But, with the 3 big options (EndlessRPM, XLR8, HeelToe) I don't know if any of them are the right ones. I'm willing to delete the 3rd cat if it will help overall performance. The j-pipes that remove the 3rd cat do cost more though I notice. If I can get good performance with just a main j-pipe and keep the 3rd cat, and spend less, I'm up for that too.

I've read most of the topics here about j-pipe, and it looks to be up & down. Some notice a difference in power in different RPM bands, some say the j-pipe made no noticeable difference over the stock one. What say you fellow members, is my best option for a daily driver in city traffic?

any of the jpipes from the big 4; rv6, endless, xlr8 and atlp, will do the same thing at the most basic level.
what I think is happening is that you're over thinking this x10.

also, our cars make PEAK power at 6000 RPM, so if you DONT EVER drive at this RPM, a jpipe would be kind of pointless...

adding a jpipe will increase hp but more so at that specific RPM range

Butt dynos are unreliable. The numbers don't lie. That's all that needs to be said.

Don't over think it, pick whatever you want. I bought an RV6 j-pipe since I have the exhaust. I take dyno's at face value, their just a measuring stick, your car may not make as much power as someone elses with the same mods.

There are a lot of comedians here on Azine

The only things the stock one is well made for is noise emissions and hydro-lock protection. It wasn't designed for max performance. It was designed to be quiet.

^actually, it was designed to be the best compromise between all three...power, NVH, and the hydro-lock

polobunny

I believe most people find it suitable as it is not terribly restrictive as opposed to many other cars stock intakes. Nobody said it was suited for maximum performance.

Thanks for the responses so far. At this rate, maybe I'll just buy some all-weather mats, and door visors and call it a day LOL.

thoiboi

you're in stop and go city traffic, why bother with j pipe

rexflexall

Mainly for the weekends when I can take her for a small road trip and such, or if they send me across town for some computer work.

thoiboi

you get paid based on how much HP your car has?!?

You're not going to reap a single tangible benefit from just a j-pipe alone. The car won't sound any different, gas mileage won't be any better, and you certainly won't feel the 5 or 6 or even 7 or 8 horsepower you gain. If you're not planning on doing additional mods, I'd use the $400-500 for something else.

rexflexall

Much thanks, I think you've helped push me in the direction the most of staying stock for now. Maybe I'll save up money for additional mods down the line, and not do anything major until I'm closer to actually paying the car off. That'll be a year or 2.

Until then, roof spoiler, all-weather mats, and door visors here I come!

even if i wanted to keep it mostly stock, and could do one performance mod, it would be the jpipe. i think it's well worth it, IMO

ExcelerateRep

I agree with sockr1. The growl adds a nice dimension to the exhaust note, and you pick up a few extra horsepower. You will see better gains with a full exhaust, but it certainly doesn't hurt to free up exhaust flow. Depending on your butt dyno, you may actually feel some better pickup. Plus it doesn't throw a check engine light, so you'll (most likely) still pass emissions.

Lol, he's not gonna feel 5 or 6 horsepower in a 3670 lb car.

especially if he never drives up to 7k RPM.


if I dont hit vtec at least once a day, i feel like i let my honda down.

Well OP, I have the ATLP V2 jpipe and to me it was worth every penny. It gave the exhaust a (subtle) nicer note and I got +1 mpg. So you get better performance, better MPG and a nicer exhaust note. Simply the best of all worlds. IIRC, When i was researching for jpipes i found that ATLP V2 made its best power in the lower RPM range, which is where i wanted it to be and why i bought the ATLP over the RV6 where its gains were mostly seen at top end. Good luck with your decision.

rexflexall

It's not that I never go over 6000 RPM, I just don't get a chance to do it on my normal commute to work because I'm all city.

But on weekends where I get to hit an open freeway, even with the automatic, I still make it a point to get that Vtec going....

FamilyGuy

Some j pipes gain in the low-mid range, not just up top in vtec, which you would enjoy in your daily commute. Food for thought.

rexflexall

Yep, thanks to Outl I am considering the ATLP j-pipe as well, costs a few hundred less since you can still keep your 3rd cat if you want. Or just buy their extension to get rid of the 3rd cat for a bit more.

Over time I will consider other things to add, right now I just want to maintain it and add a few OEM accessories.

Also, if you want to delete the 3rd cat like wound up doing a few weeks later this was the best budget option i found:
This again helped with slightly enhancing the exhaust note as well

Oh and here is the link to ATLP V2 Jpipe: http://www.heeltoeauto.com/atlp-v2-j...-es0004v2.html

Our J-Pipe dynoed 15hp, but given the car is a bit on the heavy side it may be hard for some people to feel the difference.
