If you have a custom exhaust or another aftermarket exhaust, you�ll need to know the pipe diameter for the location you are planning to install the cutout for optimum performance.

Customers with dual exhaust: Check below for our dual kits - they consist of two cutouts and a single switch wired to both cutouts to control them at the same time. This is easier and less expensive than buying two of the cutouts separately and having to wire them together.
