I bought the World Sport (turbo sized: 80mm/ 3 inch inlet) Apex-i muffler for my f22a1 turbo project and Im trying to decide whether to run 2.75 or 3 from the dp back because in the future (couple years from now) Im going to build an H22 for boost but right now Im running 8 psi on the F22a1...lemme know what u guys think

I'd just go with the 3". Might as well.

do 3", itll sound nice with that apexi. plus you wont have to go through the hassle of redoing it in the future.

I agree, 3" will work just fine now and will be perfect later

yers 3"is the way to go, I have a d16 wth a t3/t04E and a 3" downpipe and exhaust,works great, but will you have the room for it?

3" why go any lower.
