Granatelli 2.5in Aluminized Mild Steel Manual Exhaust Cutout w/Slip Fit/Band Clamp

If you're looking to change up the sound and flow of your exhaust system on the fly, this manual exhaust cutout from Granatelli Motor Sports is a solid option. It's designed to be installed in your exhaust piping, typically right after the catalytic converter and before the muffler. When closed, exhaust gases flow through your muffler as usual. When you open it up, the gases bypass the muffler entirely, giving you a much louder, more aggressive exhaust note and improved exhaust flow.

This cutout is made from aluminized mild steel, which offers good resistance to corrosion for everyday driving. It features a slip-fit design, meaning it slides directly into your existing exhaust pipe, and comes with a band clamp to secure it tightly in place. The manual operation means you'll need to get out and manually adjust the lever to open or close it, which is a straightforward way to control your exhaust sound without complex electronics.

Keep in mind that this part is not CARB approved and cannot be shipped to California. It's a popular choice for those who want to switch between a quieter street sound and a more open track sound easily.
