What does exhaust resonator do?
I'm trying to lower my EGTs. I get conflicting opinions on just removing the muffler or removing muffler and resonator. Talking to friends I get different answers on purpose of resonator.
Also is it a big contributor to back pressure?
One friend said just cutting out the mufler will accomplish about 75% of what I want to achive. . Bases this on fact I have a 3 inch exhaust brake (which I don't want to replace) so going to 4 inch exhaust pipe won't help all that much as compared to just removing muffler.
