[JSPERFORMANCE]

We usually install the cut out on the pass side tail in place of the restrictor plate assembly. This kind of makes it like a variable disc. Wide open it will bypass the muffler and closed it will shut off the pass side tail. The one you bought is designed to go there. If you want to bypass the cat we can use the one you have but it might not be of optimal size to do what you want with proper ground clearance..
