Hey guys need your imput. I am going to be running a d15b with intake header and exhaust. My question is what way will i get my maximum potential (aka. not much). Also what size of muffler would you suggest i was thinking 2.5" to 3.5" outlet? Let me know what you think also if there a specific brand i should go with i want to go with Apex'i N1

nah not looking to build but if i get an apex'i n1 muffler would 2.5" inlet to a 3.5" outlet be too big?

if you can deal with bad smell/fail smog test/bad sound then you can swich your cat for a test pipe. But it would be much more benificial for you to get a high flow cat. imo you shouldnt go bigger than 2.5" exhaust pipe. and either an ex-mag/greddy sp2/apexi ws muffler would be good .

ok so if i do the 2.5" inlet should i go 2.5 clear back to the header or should i go like 2" and then build up to the inlet?

A 2.5" inlet and 3.5" tip would be fine

slow_redcivic

ok but what about the piping from the header to the inlet? 2.5" or 2"

1993civicex

2.5
