Does bassani have spark arresters? How about this supertrapp. i know its legal, would it work with a 200x exhaust if i cut the muffler off and clamped the supertrapp on? Its says 11/4" and i beleive the o.d. of the 200x pipe is that.https://uploads.tapatalk-cdn.com/20190828/b295e8dbeb80135d0bb8a5c3808eee0d.jpg

Back in the good ol days you could buy a Cobra Sparky for darn near any size pipe. They're hard to find now. If you have the stock exhaust on your 200x then you should be good to go as far as a USFS approved spark arrestor. Unless someone has gutted your stock silencer open.

All Supertrapps are USFS spark arrestor approved by design. Whether or not it's stamped onto all the muffler bodies, IDK. The aluminum and stainless steel ones I have, are stamped that they meet USFS spark arrestor approval. Some end caps may have it. I'm certain the stainless ones I have do, but the thick aluminum end caps don't.

Just an FYI, the discs on the end do very little to attenuate sound. Ever hear a Ford 300 I6 with headers, straight dual pipes and just Supertrapp discs on the ends? It's not quiet by any stretch. At full song, it sounds like a sack of rabid raccoons dropped at ground level by a Messerschmitt 109.

If you want the quietest Supertrapp you can get, use the longest body possible. The body is nothing more than a perforated core glass pack muffler. That's what affects sound levels more than anything on one. The longer the body, the quieter it will be. Using too few of discs to lower the sound just hurts performance. I think the minimum they suggest is six discs.


I really like the oval disc mufflers that used to be available, like the FMF Megamax.


Overall, it's just a muffler and with a little ingenuity, you can put just about anything on a 200X if you already have a headpipe. Some places may have dB limits, but for offroad use, it's mostly about the spark arrestor.
