I'm in the process of ordering parts for my swap, i'm not sure what parts to get, any help would be greatly appriciated. I'm pretty sure the catback would be for an eg hatch, I'm also getting a hi flow direct fit cat and a header, the cat i'm pretty sure would be for an eg civic too, but i've heard several different things for the header, i've heard i should get the one from a 99 si, a 93 gsr, and a 94+ gsr, then i heard that the integra headers are too short, and i have to get a custom pipe made, anyone know? also if anyone with experience had any other tips before i attempt this i'd appriciate that too.

i almost forgot, which intake should i use, i'm just gonna get a short ram AEM since we get a lot of rain, with the short ram i didn't think it'd matter much but i thoulght i'd ask anyway. thanks

well, if you have the gs-r intake maifold, you will need an integra gs-r intake. Or if you have a skunk manifold or Si Manifold you will need a 99-00 Si Intake. About the header, I have a b20/vtec in my 95 coupe and an aftermarket GS-R header was too short, there was a gap of a couple inches between the header and the cat, so I just took the cat off and made a test pipe to connect the header to my exhaust. Hope that helps a lil.

I believe you can use high flow cats from 92-00 civic/94+ integra because they fit the same. You can see why stores say "civic/integra" high flow cats when they sell it. Just use an intake for the civic because that's what i have on mine with b16 (should be same with b18s) (obd1 though). About the headers, you can use the stock one on the b18c motor swap if it comes with it. heck, you can use the type r one (forgot which years). I heard b16s are shorter around the block than b18s because of the block itself, so might want to do some research on this.

i don't really want to install a test pipe, i want to stay emissions legal, and if the stock header works, how come the aftermarket ones' don't? i could just try the 95+gsr header, and if its too short i have a welder, i didn't want to have to do that though
