On my Hellion Saleen I just had a custom 3" exhaust welded up with Borla S-Type mufflers. It sounds good, but it is surprisingly quiet. This is my first turbo mustang, from what I've been told the Turbo really quiets things down. I'm currently scheduled to have a electronic cut out installed off the down pipe by my fab shop on Monday. What are you guys running for exhaust and how's it sound? I'm sure the cut out will wake the dead, but I may want to swap out the S type mufflers for something a little louder. Looking forward to your input.
