Getting a new muffler and want to make sure it will fit. Says it's for a Prelude and has a 2.5" intake.
I believe stock is close to 52mm. Are you getting just a muffler or a catback system? If it's catback it won't really matter because the new piping will bolt up to the factory cat.
Also, what does a 2.5" intake have to do with exhaust?
