My 99 Scrambler has what appears to be a custom exhaust. The muffler is made by Dynomax and from the looks of their website they only make exhaust for automobiles, at least now I don't know about the past. It has an exit pipe that is 2 1/8th OD. Is anyone aware of a bolt or clamp on spark arrestor I can buy so I can be legal here in Texas? I really don't want to buy a whole new exhaust system right now.

 

I think you would be better off sourcing a used stock pipe. Many guys have their stock pipe cluttering up their garage after an upgrade. Check ebay.

Is this a 400 or 500?I think the Dynomaxx may have been an early HPD.
On the 400s you can use a stock muffler or a FMF TurbineCoreII silencer.If the pipe and silencer are made together find a stock system off ebay cheap or get any used brand except DG FMF is ok but hard to get clutching right on them.

 

It's a 500.

 

With the 4 stroke (500) you just need to get a slip on exhaust. (muffler) White brothers is one I've had in the past. Was ok, had some issues with the weld into the exhaust, but 10 bucks at a weld shop fixed it.
