    Rated 4 out of 5 by from Good Fit I installed the 21002 Hooker Headers mufflers into my side pipes. The results was as expected a quieter exhaust sound that still sound good. The only improvement would have been some instructions on how to remove the muffler insterts that where already in the side pipes when I purchased the Car.
