4" mufflex installed pics Okay finally got around to installing my 4" mufflex system .It sounds great for a stock LS1 with just KOOKS and no cats.
Went over the axle with room about 1/4 of room to spare no rattles or banging while driving and also about 80% of the rasp is gone which I hated with the GMMG i had on the car.Now to get back to the track to see if hurt me or helped either way I love the sound much better.
