Hey Guys! I know this sound stupid but, how do you remove
the bottom of the muffler? I tried unscrewing the two screws on the
bottom and it still wouldn't come out? And after I take it out then what should
I do to make it go faster? I've done the break-in period (1 Gallon) but I'm sure
I have not gone 200 miles yet and it only makes it up to 27mph on flat.
How do I make it go faster?
