Custom Exhaust
 

Whats up yall? I am new on here, my brother has a 93 Eldorado with the 4.9 V8 and its stock right now. We are just finishing a project on my car and are about to start on his car. I know theres no aftermarket exhausts but we want to open it up, anyone done like a custom 3" exhaust or anything similar? Thanks for the info.
