GM Performance mufflers
Hey everybody I have a set of GM performance mufflers for sale. So if anybody is looking to make their car sound way better than stock, pick up a few HP and still keep it under warranty this is the deal for you. Retail $850 new. I am selling for $400 only 7000 miles have been put on them.
The reason I am selling these is because I upgraded my exhaust long tube headers and 3' exhaust no cats SOLD
