the down pipe connect to my stock cat is too long, should i ban the pipe or get a after market high flow cat that will fit perfectly ?

 

 

which one should i get ?

 

my friend is using a 3" carsound. no conpliants yet

 

but can i still use the stock exhuast ?

btw do u know any 2.5 exhuast that's really quiet for turbo R, i just cant stand loud exhuast

 

Cut the drag downpipe to fit the stock cat.

If you do this, you can use off the shelf cats and exhausts.

 

i dont think you can use it.

my friend has a custom 3" catback with a 3" turbo apexi n1. it's quieter than my 2.25 5zigen catback. the turbo itself will muffle the sound quite a bit.

if i were you, i would get a 3" catback. it wont be that loud and you'll get better #'s from it.

I wouldn't use the stock exhaust for your turbo application. It's too restrictive and you'll be happier with an aftermarket exhaust.

 

but i wont be too happy if the car is too loud, dont like to talk to cops all the time

 

the DRAG downpipe is meant to be cut to length

asfar as exhaust goes, just get a 2.5" cat(if you feel the need) and make a 2.5"
exhaust with some sort of straight thru muffler.

 

thermal makes a 3" exhaust that i've heard isn't too loud

 

I'm the friend

I got a 3" carsound cat, i had the down pipe widen to fit a 3" carsound with flanges, and custom madrel bent pipping all the way through with flanges seprating the cat from down pipe, mid pipe, and axle back to muffler so when i needed to i could piece off the exhaust system. And trust me 3" inch is worth it! for future mods allowing more flow and it is not loud really, the turbo is going to muffle the sound down, and you kiss that N/A sound good bye your going to have an distinct sound of an turbo honda, plus turbos create huge amounts of backpressure and don't need it, turbos love to flow freely, the only reason i have a cat is because i want to be street legal in some way and i live in so-cal.
