I have an jdm obd1 gsr swap in my 94 civic cx hatchback and don't know what exhaust to get beacuse the piping on the gsr is 2 1/2 .. I was thinking about going 2 1/2 or even 2 3/4custom piping all the way with an type one titanumin muffler. (can be found at http://www.aj-racing.com)

My friends think i should do the 2 1/2 piping then got with the universal mufller of skunk 2, or hks hiper, dunk, or even apex'i n1.
Also what piping size would be best?
Also should i gat an cat. convert?

any suggestion would help me alot.
thanx

 

your car should have a cat. converter. and depending on your setup, usually 2.25 is good. if youre gonna have a nicely built engine 2.50 is good(cams, i/h, other stuff) turbo = 3inch. and as far as muffler, a lot of peeps like the apexi.

oh wait - i think you meant GUT the cat convertor. No. It will sounds raspy and crappy. just take it off and replace it with a resonator or glasspack. thats what i did, sounds great. Hope this helps

 

my car is stock right now with just an intake.....just bought jdm it cams and jdm itr 4-1 header, going to put in next week .......with a moth going to built my head and port and polish it........and thinking about going turbo in 2-3 months when getting my income tax back..

ull want max. exhaust velocity after the cat. ..so unless ur planning a turbo stick with 2 1/4..getting too big will hurt performance

2.5", mandrel bends, and some kind of straight-through muffler. the material is up to you ... shiny SS, non-polished SS, aluminized, etc. non-polish SS is good for a sleeper look while still being durable. Check out ES mufflers, Magnaflows, and Borlas. A'PEXi is also good if you like the canister style. i prefer oval mufflers, but that's me.

EDITED for spelling.
