This pipe is terrible....I want to cut the muffler off until I build a expansion chamber

Yes it's not good but the muffler is actually the only part that does work well! the flex hose is the problem the I.D of the fittings is way to small not letting the exhaust flow thru at usable rate!

I cut the fittings off at both ends and tried to hog them out!but they only opened to 9/16 still to small!
