    Comments about MagnaFlow Stainless Cat-Back System Performance Exhaust Kit for Chevrolet Impala:

    I wanted a complete Cat-Back exhaust system for my 2007 Impala SS,since I had to replace the stock mufflers due to rust. This kit fit perfectly. The sound is great to me, which is a mellow growl. But once you put your foot down it roars to life. I have noticed an increase in horse power and fuel economy. I'm so happy I didnt go with the other top brand, which to me is just a bunch of noise. If you want performance then this kit is the one to get. Also, I dont detect any drone when the engine goes from 8 cylinder to 4 cylinder mode (D.O.D). Once the mufflers break-in the sound gets a lil deeper. Now it sounds like a BEAST.

    • Q:

      In this kit is everything I need to immediately install it onto my vehicle included? Or do I need to purchase separate gaskets and clamps separately?

        I'm glad to assist, New2Repair! Everything you need to install the system is either in the box or already on the vehicle.
