    Description

    The Impact of Dual Exhausts. Give your Sierra visual and sonic impact -- along with a performance boost – with this dual-exit cat-back by Gibson. The aggressive dyno-tuned sound must be heard to be believed, and average power increases of 15-20 peak HP are not uncommon. Stainless-steel construction resists rust and corrosion. This is the dual-exit cat-back good enough to be called a Gibson.

    Built for Power and Durability. Gibson uses high-quality stainless-steel 1.75-inch diameter tubing. The header tubes are tuned for maximum and ideal flow characteristics. The sound gives that aggressive bite expected of a dual-exit system. Gibson covers this exhaust under their lifetime warranty.

    Headache-Free Installation. All necessary hardware and gaskets are included for a smooth installation experience. This system uses stock hanger locations wherever possible. Follow the fully-documented, step-by-step installation instructions and start enjoying the benefits.
