Muffler Delete, the good, the bad, and the ugly

Did you lose any power with this configuration? I know some BMW's actually lose a few bhp when done.

He didn't lose any power if he did its very very negligible (read 1-3 hp)
Reason being your biggest restrictions are in the Cats which is also why it is not that loud even after deleting the mufflers.


I have deleted the mufflers on my stang and many do they sell axle back kits for the sole purpose of just deleting the mufflers. It isnt until you start cutting Cats off that it gets loud.

Case in point my brothers stang, same car as mine only he went with a Bassani race axle back ( a straight through design with resonated tips) Well when we put on his off road H-pipe (an H-pipe with all the cats removed) his exhaust became unbearably loud and we had to slap my stock mufflers on his car which "muffled" the sound down to a bearable level again.
