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

 

go with apexi world sport 2 it workd really great with my sohc!

 

Ok what size? and should i do full exhaust from header back and with or without the cat?

 

maximum performance no cat and go from headers back but its also illegal think about what ur going to need aka smog in the futer anytime soon? also man think about the envirment and the lil bunnies ur going to kill the bunnies man!!!!!! lmao jk

if u wanna build a motor i have a d16z6 block and parts and a y7 long block parts ecxpt for the block for sale 600 pm for details

 

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

 

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

 

2.5

 

alrighty thanks guys
