Will it hurt hurt anything to run without the spark arrester?
And spare me the enviro-babble! Just ask'n, cause mine got caked with mud and it sure sounded better with it out while I was cleaning it.

What is the replacement pipe of choice these days? And who sales it the cheapest or maybe with a pipe and jet combo?

HMF Utility is the one a lot of us use. Power & sound all in one pipe.

It does sound cool. When I cleaned mine I rode around for awhile be fore
I put ti back in. I am sure you need some back pressure on the exhaust or you will burn valves. Not sure if it will hurt or not.
Like RR said, better to go with a pipe.
