how to shorten a pipe?

[Glenyzracer25]

what is the best way to shorten an exhaust? i have an HMF i am considering cutting,but want to know exactly is envolved. any advantages or disadvantages?

drill rivits. unbolt/assemble exhaust. cut the can to desired length with saw. repack. reassemble. rerevit. bolt back on.

advantages: it sometimes looks cooler. thats about it. some claim better bottom end.

disadvantages: its annoyingly loud.

i personally dont think its worth it unless the exhaust is gooberishly long.
