OK guys I think a few of you have had this issue. At first I thought it was a clutch issue when I was in Dumont dunes, I couldn't get past 7500 rpm.

Obviously if you start to feel power loss or limited RPM but no warnings, lights, other issues. Just the motor boggs and can't go FAST! Ha Ha, check your TIP.

Dean, my buddies said it sounded funny when plugged (muffled, banana in the pipe) and then normal (ugly rasp) once all that debri was removed. Easy phillips screw removal and plyers to put the heat/rust welded tip.

Now with the the spark screen removed it sounded WAY better, deep tone bop bop bop from the cam. I never drove it just rapped it a few time to be sure all the debri had blown out.

as a former deanie law for 30 years I wouldn’t want to be the cause of a forest fire as the draught plagued west has enough of them...

That is why I won't remove the panel behind the muffler. Park or backup into high grass and the catalyst can easily start a fire.

I'm actually surprised with a lot of the aftermarket pipes not being true compliant without screens, people tend to think the turbo or baffling inside is legal

Regarding mufflers being a legit spark arrestor: An approved spark arrestor is serviceable, to remove the carbon trapped by the spark arrestor. There are mufflers with screens built in - Hushpower II comes to mind - but with no ability to service the screen, they don't qualify as a spark arrestor.

The only turbos that don't need spark arrestors are ones with no ability for exhaust to flow around the exhaust turbine. I'm not aware of any turbo systems that don't have a wastegate of some sort, either internal to the turbo or external on the exhaust header, so they all require spark arrestors.
