sorry didnt know if this should go in the turbo section or exhaust section.

I have an apexi ws2 catback exhaust that is 60mm.

I'm going to be running my turbo at 7psi (daily driver) I love the exhaust because of the way it looks (non ricey) and the way it sounds (on the quieter side). will I need an 80mm exhaust?

60mm is about 2.36", which is a bit small for a turbo setup. I'd bump it up to some custom 2.75"/3" piping

i appreciate the response but...

do i have to??:(

lol.. I love my exhaust.... what are potential consequences if I leave it? Just might rob some power?

I called this shop that does turbo installs and stuff and they said as long as im not runnin over 10 psi then I shouldnt need the 80 mm exhaust

Most people go at least 2.5, even for a small setup. If you really don't want to, then try it. It will be a bottleneck, but if you really like it, then go for it and see what happens.

Just put a high flow cat on it, that will help a little bit:)
