For a strong boost in power, the Invidia pipe offers an alternative to other power-boosting enhancements.

Each Invidia pipe features a large 4-in stainless-steel Bell mount to enhance power by fe excess gas. It sports a one -piece design, eliminating the need for the stock catalytic converter. In addition, each Invidia pipe can be bolted up to any Invidia exhaust or a stock exhaust for an easy installation.
