Exhaust Cut-Out

Adding a second outlet farther upstream in a single exhaust system offers a "quick escape" for exhaust gases, thereby producing gains in horsepower and torque. Anti-noise regulations limit use of this cutout to racetracks only.

Adding a second outlet farther upstream in a single exhaust system offers a "quick escape" for exhaust gases, thereby producing gains in horsepower and torque. Anti-noise regulations limit use of this cutout to racetracks only.I am the owner of the black 1998 Trans Am that is in the install video for this product. These cut outs are a lot of fun and did give me additional horsepower. I picked up a mph at the drag strip when I have these open versus closed so I'd say its a solid 10 horsepower and I have an already very non-restrictive exhaust system. The car has ported heads and a mild cam so when they are open its VERY LOUD. My neighbors hate me. Its just a tiny bit quieter than running open headers.
So far they've been on the car for two winters and the hardware is not showing any real signs of rust either so the stainless steel is doing its job. One thing I did that helped was I had the install bolts welded to the flanges so that to open the cut outs I do not need to use a wrench. Just loosen the wing nuts and pull the flaps off the studs. Takes about 4 minutes to open or close both cutouts since I have 2 of these. One welded behind both headers in the Y-pipe.
