3 INCH turbo back?

[NORCAL SS]

Just seeing if I can do a 3 inch turbo back exhaust and be ok or will I need a custom tune after?

Also not sure if anyone make a 3 inch turbo back or will I need to fab one up.

Are you talking about the down pipe back or catback? Sportmachines makes a 3" downpipe

If you go full 3" with no cat your going to have boost control issues..... so plan on going to an external wastegate. I think some guys have had luck with upgraded wastegate actuators but ive never personaly used them
