"Very nice system had it installed by a local shop and they said it was one of the best systems they have seen.Easy to install and very nice looking.Will take a little time to get use to as it is louder then the stock system but so far I am very happy with it more power and better mileage." —Dante S from Clinton Township, MI bought a Magnaflow Exhaust Systems for a 2007 Chevy HHR.
