I have an R33 GTS-T with BOS front pipe, Catco cat, Trust PE2 cat back and it is a bit too quiet. It is a full stainless steel system. I want it a bit louder. I was thinking of cutting out the muffler and putting in a bit of 3" pipe but after reading on here that would probably be too loud.
Is my only option, without getting a new catback, to cut out the old muffler and weld in a new smaller louder muffler?
