Dremel.....you want a perfect cut so everything lines up nice again.

 

Im not to much into shorties but in you case it should be cut down some.

 

if you have access to a big enough chop saw then use that, i cut down my bros r1 dual pipes and both cuts were perfectly straight thanks to the jig on the saw that held it tight. left my pipe alone sounds perfect and i dont want it too loud

 

if you use the cut off wheel take your time and get a good mark to follow and you will be ok then use a fine file and get the burrs off.

 

A friend of mine has a chop saw, and he's cut several silencers before so that's what I'll use. Still haven't made the time to do it yet. Hopefully sometime this week. I'll post pics as soon as it's done.

 

Just use a good iron saw to chop it down.
I chopped down the Devil exhaust on my previous bike, and the Arrow exhaust on my stuntbike.
Sound was good, looks were great. Just work precisely.

Right now i have a TBR can, new model, chopped down in the factory on request for -5 inches
