Anyone with a dual-cat exhaust have, or know of any, vendors that provide exhaust dumps for pre-muffler installation? Toying wiith the idea of installling an electric cutout before the muffler on my 97SS, dual-dual system.

Just thought it might relieve a little back pressure and give me some extra power when I want it.

Any thoughts appreciated, esp with regard to the benefit if any to be gained.

Thanks.
