Okay so I'm looking to eventually go with the j-pipe, PCD and comptech exhaust...

I already have the exhaust on it's way. I'm wondering if this is the smart way to upgrade... like exhaust first then do the PCD and j-pipe. I plan to do the pcd/j-pipe at the same time once I have some cash to blow.

I was thinking to avoid bottlenecking I should do it this way, comments?

Thanks guys

 

Depends on what your finances look like, in all honesty. J-Pipe will be your best cost to power ratio, so I would start there.

 

Wouldn't I get less than peak gains from the j-pipe without the precats and exhaust anyways?

 

If it was me, I would start with the Jpipe or PCD because of exactly what DeathMetal said, but it's really up to you. It's your $$

 

Yes, but any increase is obviously an increase, and you can always add on over time.

J Pipe is the most effective SINGLE mod, I think you're doing what everyone does and tries to go a little to hard and heavy out the gate (we've all done it)

 

^^^ exactly...whatever you do....get the jpipe....

i took the wrong route and am missing serious low end power.....

 

How are you missing low end power did you purchase and install the PCD? Thats what I'm debating on, if I should get PCD or not. I've tried searching the threads for information, but couldn't find anything. Plus I don't want "the rasp" everyone is complaining about.

 

pcd, jpipe, catback exhaust.
i would do it in that order for best gains and less labor. if you do jpipe first you will have to take off again (3 annoying bolts that might need to get torched) to do the pcd...unless you get both at same time. don't let the rasp from pcd scare you away from buying it. the rasp can be fix

 

There is a little bit of rasp with the PCD but you can get rid of that when you get a full exhaust....

well am missing low end because i have the following setup:

CAI, TB spacer, Plenum Spacer, PNP intake manifold, MDX Spacer, PNP intake runners, PCD and then the damn stock exhaust LOL.....so its clogging the free flow up....i think once i get a jpipe or go a different route i will get the missing low end back

 

Haha, well I'm glad i posted here AFTER i bought the exhaust.

 

A good exhaust will net you 10 hp/tq. It will also improve the aesthetics of the vehicle and the sound.

If you're looking for mostly performance, the j-pipe is the best bet. We saw gains of 10-15whp and 15-20 wtq with our j-pipe.

Thanks I plan on purchasing the j-pipe and PCDs, I just wanted to do it gradually and In a sequence where I wouldnt see any side effects...

 

Dude I would not worry about how you add components. To me it's just fun to modify the car regardless of the order and sometimes the logic. My exhaust started with a j-pipe then the aftermarket resonator mid muffler delete. Now I am about to add the precat deletes. If I still want more I may change out the mufflers and piping with a custom setup. I am not big fan of the prefab exhaust out there for our car and they are out of my budget.

 

^^^ i think what the OP was asking is....if he ended up getting PCD's and catback exhaust he will notice gains but not as much....since he is bottle necking in the middle....

i think the right way to do it is: PCD + JPIPE and then CATBACK....if you have the funds go all out.....

 

Def. get all three together PCD, J pipe, and cat back. The most gains i got were through my PCDS.

Hey "swoosh" u might want to get rid of that mdx spacer mod when u get a full exhaust because the mdx spacer mod combined with the PnP of ur manifold and runners will hurt ur top end supposely. Look at this thread post#8:

https://acurazine.com/forums/showthr...ntake+manifold

 

hey yonkers yeah i did read that thread and i got my runners and mani pnp'ed by Gerz and hence and guessing moore's....

i need to take the mdx spacer out....but i wanna do it pending the dyno so i know thats the real culprit....

also i have the butterfly taken off from the intake manifold....so dont know if that will adversely affect me....

 

wow lol nice. let me know what the dyno results are when u get them!! does it feel different with the butterfly out?

 

actually yeah....i installed all of those along with PCD's and i was spinning thro 1st

again my 1st gear is super strong....the pull is awesome....where i loose power is 2nd/3rd gear from 2-4K rpm....

once vtec kicks in i can feel the bottleneck

 

wow lol thats crazy

 

So if i get jpipe, PCD, and comptech exhaust what issues would I encounter? Id definitely get the smell, but what about rasp? Would i need a resontaor?I would probably wait until after my next inspection in Dec to avoid any emissions problems.

 

along with jpipe + PCD + comptech exhaust I would also get 3rd cat delete, resonated version.....

yes its going to smell but then again you dont want to bottleneck ur exhaust.....

comptech is one of the quieter exhaust (i think, so dont quote me on this) so you wont need a resonator, besides you already have a resonator + 3rd cat delete

 

Well id get rv6 j-pipe... SO i'm thinkin rv6 precats and jpipe with comptech exhaust... Would i loose any gains with using v2 and an ATLP race pipe instead?

 

Okay so I'm about to order rv6 j-pipe v3 and PCD v2 combo... this gunna work well for me with comptech exhaust?? SOmeone confirm for me before i back out

 

if you want to completely eliminate the 3rd pipe and get a little more gains:

rv6 precats + rv6 jpipe v3 + rv6 exhaust.....i think he will hook u up with a good price and the exhaust sounds good and gives one of the best gains
