Granatelli 2.5in Stainless Steel Manual Dual Exhaust Cutout

This Granatelli dual exhaust cutout kit uses 2.5-inch diameter piping, which is a common size for many performance exhaust systems. It's made from stainless steel, so it's built to handle the heat and moisture under your car. This kit lets you manually open or close a section of your exhaust pipe, typically right after the muffler. When you open it, exhaust gases bypass the muffler entirely, giving you a much louder, more aggressive sound and a slight increase in exhaust flow. Close it up, and your exhaust runs through the muffler as normal for quieter operation.

The manual operation means you'll use a lever or cable to switch between open and closed positions, giving you on-the-fly control over your exhaust note. Because it's a dual kit, you get two cutouts, one for each side of a dual exhaust system. Installation usually involves cutting a section out of your existing exhaust pipe and welding these cutouts in place. Remember, this part is not CARB approved and cannot be shipped to California.
