Noticeable rumble when idling. More growl at low rpms. Drone is feint. Sounds nice with my supercharger and brute force intake. Very satisfied with my purchase.

I am dissapointed in the sound that the exhaust system produces.However I probably shouldnt expect to much from a six cylinder engine. As far as gas mileage goes I haven' noticed any improvement yet, maybe a little more power

OUTSTANDING! Installed a cold air intake the day prior and could feel and hear the difference...but, I had know idea how much better it would get when I installed the Magnaflow exhaust. Except for significant pains in getting the stock system off, installation was a breeze. The Magnaflow bolted on smoothly and everything lined up. My little 3.3L six cylinder now has a throaty roar and instant throttle response.

I was very impressed with the quality and the fit was truly better than the factor fit. Sound is just right, not to loud. Power increase definitly felt.
