My exact experience here.....What little difference you might get out of "mufflers" is no big deal...Beave said:I have the FM 40 with dual outlets on my truck. I ran 3 mph faster than another titan at the track who had a magnaflow, we both had aem intakes other than that. My muffler was on the truck when i bought it so idk from experience the difference it makes or if his truck is just slower for some other reason.
