I'm selling my borla and I'm gonna go with larger piping. So far my only option is to go with trubends stainless steel 2.5" with a Borla muffler and tips that look as close to my current borla tips as possible. It sounds like everyone's exhaust is too loud though is there anything I should look at to quiet it down a bit? I remeber hearing something about the Borla mufflers only coming in one size inside even though the inlet and oulet were size to your application. Is that the Borla muffler on this system? Is it 2.5" all the way through?
