No Spark Arrester

[Moto92]

Just wondering if there is any harm in running with the spark arrester out of a pipe. I have a T4 and took mine out today to clean it and decided to go for a spin without it. That thing is hella loud now, you wouldnt think some little screen could do so much.

No harm and on "opened up" pipes such as the t-4 it will do it some good although it may call for a jetting change...

As long as your neighbors are very into 4-wheeling, I would suggest not doing that. It only takes one pissed off person making one phone call to close a lot of riding areas.
