im looking for an exhaust bypass valve that can be electronically controlled. To better explain myself, in one mode it would run through the cat and muffler, in the other mode it would open a gate and run open downpipe. yall heard of these right? I used to know a guy who had one on a grand national

 

it is called an e cutout. try searching for that, i think there used to be a guy on here selling em.

 

quicktime performance makes one
