I have the MS pipes. Everything else in the exhaust is stock. I like them. The car has a bit more raw/rasp attitude, but not over the top---not enough to get you in trouble when cruising. A Highway Patrol officer SERIOUSLY eyeballed my car a few days ago while cruising in freeway traffic going below the speed limit. I was totally chillin' and had been chillin' for the last 20 miles. He was looking to ticket someone----he checked my front bumper for a plate, he cruised behind me, in front of me, turned all the way around to look back at my car when in front of me. I mean really......I was just cruising along with everyone else. I have no tint, the front plate is on the tow point. If the car had been loud, he would have gladly pulled me over, because as soon as he was done with me, he got behind a pickup and pulled him over......so, I can say with certainty the test pipes raise no issues when cruising around. But when you get on it, it has a nice direct sound.
Have you seen this comparison?
