I have a 17 TA and yes the stock exhaust sounded really nice but not loud enough. I put 24250 minis in place of the mids and yes louder but at WOT with the windows down it sounds like crap after say 4000 rpm. Blatty or popping sound like a harley with shotgun pipes...especially noticeable with the sound echoing off a building etc. I noticed this with the stock exhaust but just not as much. Is this due to an x pipe instead of an h pipe? True duals on my chevy 350 pick up sound sounded like pure junkyard trash until I put in an H pipe and then pure bliss. Im used to the sound of a fire breathing 750hp BBC so my opinion may be a little skewed. Any thoughts on this?
