I have a 2007 GT with x pipe no cats an I was thinking about putting a one chamber muffler with dumps should I do that? See idk if it will sound good or not help me out guys!!!
Im doing the same thing. I'm dumping it right before the rear end with these little Magnaflows. I just need to get a different rear cover to cover the tailpipe holes
I wouldn't do it if the car is your daily driver. I have turn downs on my Monte Carlo SS and when it was my dd the turn downs would get really annoying. There where a few times going though the drive-though that I had to shut the car off so that I could hear the workers. If its not a dd then by all means, do what you like.
