start with muffler off

[charles]

[BuggyMaster]

the entire exhaust pipe including the muffler or just the muffler with the header pipe still on?

[charles]

Yeeeeeeah... I'm pretty sure that wouldn't be good for it.

[mancofunkart]

it causes build up in the cylinder

you need to have at least the pipe, if possible, the whole thing. no pipe or muffler means flamethrower, plus you will give up a little power. try unpacking your muffler, makes it sound really cool, its easy, and its free.
