Exhaust - power

Anything that fits and has a 3" inlet/outlet would work.

Cool I'm just hoping it won't be obnoxiously loud..

Hey guys, I ended up going 2.5 exhaust straight to the back, dp, mp, and boost seems to want to surpass 13-14 and beyond. I will be installing a fcd shortly cuz I am very easily hitting cut but I worry that I will still be overboosting past my turbo threshold of 14psi after the fcd... What should I do so I don't go passed 14? Is this even normal after exhaust work?
