HP gain from muffler delete only?
Is there any HP gain from just deleting the mufflers? I did it for sound purposes but I just bought an ISS Forged QES system and I am curious if I will notice a difference. Also, has anyone gone from a simple muffler delete to an ISS exhaust? If so, how was the sound difference?
