im running a b20vtec with bolt ons in my hatch, cams,h,i,e. etc. I have an Apex N1 NA canister, what piping should i run 2.25 or 2.5. im gonna run a resonator but no cat (omni test pipe). i dont want it to be to loud. can i use 2 resonators or is that too much restriction? like i said i want it to sound as close as possible to Apex n1 catback . thanx
