162-KH12 RSX-s
162-KH13 CIVIC EX
162-KH14 CIVIC SI

these are the part numbers ......i love the sound of mine and a would rather keep it b/c of money reasons and just because it is easier ...when i swap to my k20a3
they are all 60mm->115mm so what is the difference then? you think they are maybe shorter or longer?

 

u will want the one for ur car, Civic EX.

The Si/RSX have different piping paths.

 

Sorry Em2, i just thought of this.

Where u planning to use the same exhaust on a turbo'd car?

If i was u, i wouldnt upgrade my exhaust if i was gunna go turbo.

Turbo exhaust should be around 3", where N/A is maybe 2.5"( probably smaller).
I would not run a turbo exhaust on an N/A engine, or vise versa.

If u are planning to go turbo, just keep the stock exhaust untill u get the turbo on, then get a custom mandrel bent setup.

 

reason i was asking is .....a while down the road after a swap i will go turbo and then i will get the 3" ....but untill i have $ for boost i will be running the stock a3 (i already have the N1 on my car right now...just wondering if i would have to get like a new exhaust for the swap, will it line up?)

 

thats a good question. I doubt it will line up, but im sure some muffler shop can do a little cutting/bending to make it fit, so it wont cost u as much as a new exhaust, but it will cost u some.

 

well if it only has to do w/ cutting then i could cut it and weld it back together.......but i might want to sell it later
