l have a Vulcan 900 Classic, and l live in Texas.l thought about hollowing out the pipes, but l am trying to find out if there is any other way.

There is a FEDERAL law against doing anything to your stock pipes, including removing them, but that does not stop people from putting noisemaker pipes on bikes.

This in turn PISSES people off whenever they see or hear bikes. It is one of the biggest black eyes for all motorcycles.

there are aftermarket pipes that are louder and still legal. Cobra makes stuff for jap cruisers.Cycle shack makes stuf to

buy after market pipes

with some bike you can change out the baffle to get a different flow but you would still need to re-jet the bike. they make a flow master that goes in to the pipe at the jug it keep the bike compression the same and directs the flow of exhaust making the bike a little louder that is mainly used when drilling out the baffle

short answer -NO
