I have A 00 warrior with a k&n filter, jet kit ,and a fmf megamax II pipe.My last trip out I lost 2 bolts that hold the disks and spark arrestor on.My question is will it damage my engine to run without the spark arrestor and disks?Noise is not an issue where I ride.

 

I know of several people with white brothers mufflers with the disks like yours that run them open. the only problem is that you will usually lose horsepower becuz of the way that the mufflers are made. try to find some screws so you can keep the discs in

 

I have a mega max II on my warrior and run it without any discs and love it...its loud and i dont feel any power differnce. hope this helps...i really dont think it hurts you in any way.

 

The discs are for tuning, less discs = more bottom end, more discs = better top end. It would seem to me that running without the discs would allow foriegn objects into the exhaust system. Get new bolts.
