basically stock d15b, with a 75 shot of nitrous, i wanna get the exhaust redone with a apexi n1 muffler and was wondering with size piping to go with.

 

for i 1.5 i wouldnt go bigger than 2" (un less you plan on boosting it later) i went 2.5" for my dohc zc (1.6l) and it was overkill....untill i went with a turbo

 

I would go between 2.00" and 2.25"..Any bigger and you will get the rasp.

i was thinking 2.25

 

what size resonator should i go with? I want a deep soundind tone, btw there will be no cat.

 

A large one ..18" or larger.. or maybe 2 small ones,,one up right behind the header and one right before the axle-back portion..

 

i think for a n/a application a 2" to 2.25" exhaust would be just fine. If you are however going to go turbo a 3" exhaust would be the best. Also you might want to consider a cat unless you want to take off the muffler system every time you go for emissions. Absolutly up to you , just something to think about.
