    Handle the Heat. This Gibson Dual Split Cat-Back Exhaust System features a chemically bonded layer of aluminum as the finish, creating a very shiny surface that resists the discoloring effects of regular heating cycles. You'll still be getting the same performance boost out of this upgrade years from now without losing power to air leaks caused by rust.

    Surprising Power Boost. Even if you're swapping out your stock exhaust for this vastly improved design just to get a deeper and louder sound, you'll notice the power difference from the first test drive after installation. Gain up to 20 HP just with a simple swap of your exhaust lines and a better muffler.

    Streamlined Design. Sometimes you need your aftermarket parts to blend in rather than standing out. The polished finish on the tips and split straight back design simplify the look of this system. With the tips clamping on and fitting around most bumpers without the need for cutting, installation is really a snap.

    Installation. The process is moderately difficult and should take an experienced mechanic about 5 hours.
