Will it hurt to remove the spark arrestor on a stock rubicon muffler and ride without it? I took mine off this afternoon just to see if it was plugged up or anything, and while it was off I started the rubicon just to see what it sounded like and I thought it sounded pretty cool. Would it cause a decrease in power to run without it? The rubicon is stock, it doesnt have a jet kit or aftermarket air filter or anything.

 

No it won't hurt anything. Except maybe the woods that your riding in.
