Electrical cutouts and muffler deletes are two TOTALLY different things and several people have posted on here that there were no gains on the V8s, but I don't recall any losses.
I WOULD expect losses on certain vehicles with cutouts, but with the muffler being at the end of the exhaust, I wouldn't expect any losses.
Those with ACTUAL experience should chime in.
