If you payed 3 bills for a Magnaflow you got ripped...I got mine installed, cut the factory tip off, and replaced it on the new muffler for $100.00. W/lifetime warranty....and to loud..I guess I have nothing to compare it to...but I think it sounds great...I still listen to the stereo, and enjoy the wide open spaces. I could percieve a difference performance wise....could be all in my head ...but that is all that counts anyhow. People on the Malibu cruise liked it..of course they were on the outside of the car......Suggestion: leave it alone for a while, the sound does change ever so slightly with use...you may begin to like it...btw did you see any improvement other than noise?
