This may sound like a totally stupid idea, but I thought it would be cool to have an exhaust cutout in the downpipe of an exhaust.:fart I dont know if this would be effective or harmful to the engine. I figure the faster it can get out the better. Someone correct me if im wrong or share your experience if you have done this.

Surely someone has thought of this before.

Be pretty loud. No engine damage or anything. The turbo provides back pressure against the motor. After the turbo you want the exhaust out as quick and easy as possible. Look at all the sled pullers with hood stacks.
