Hi all, I am doing a custom catback exhaust for my car and I was wondering your thoughts on a muffler. What I am going to be doing is cutting out the resonator and putting a round muffler there and cutting out the back muffler and putting a sweet tip I got from family. I was looking for a nice sound but nothing super loud and annoying. Anyone else do a similar setup like this? I was looking at Borlas mufflers because I know the brand and was looking at the XR-1 line.
