Absolutely a profile is built, and rightly so. People say a lot about themselves by how they choose to portray themselves to the world, both in personal appearance and vehicle. My truck isn't the douchebag brodozer, just a slightly redneck work truck.

Indeed, part of the required design is that the spark arrestor be easily serviceable and cleanable.



Usually getting to/from camping spots and such. Usually you're right that's low output, sometimes it requires some power. Looks like the 1.5" diameter screen would have ~1/3rd the area of my 2.25" pipe. You're right at lower speeds and outputs it would probably be fine, but if that turns out to be the only option then I'll just spend the money on the larger spark arrestor.

Very valid point. I have no clue on the stock muffler for JD Gators and tractors and such.

It's an inspection for a "stock" exhaust system, or stick a 1/8" rod up the exhaust pipe and see how far it goes. Rod goes in a couple inches before being stopped by a screen + "USFS Certified per 5300IB" or whatever printed on the muffler or spark arrestor and considered good.

I'm kinda stuck two different ways. When on a forest road, it's a road vehicle and needs the stock exhaust OR a spark arrestor. When off road(where she caught me), it's a class II ATV and needs a spark arrestor, period. Whether that's built into the factory exhaust or something that's added afterwards, it needs a spark arrestor.

I checked the regs. She not only had me dead to rights, she was pretty lenient.

That might be an option for the on-road stuff. Good idea, thank you.

Thanks for the input, folks. Kind of a mess. We've had a pretty brutal couple of fire seasons here and everyone's rightly on edge. During the rainy season, I doubt any of this will ever come up.

I would not call that red neck, I call it a clean working truck that appears to be usable. Red neck would be rear window sticker bombed with rebel flag, under armor / mossy oak and Calvin peeing on something. The only thing I see hanging off the trailer hitch is a light plug so extra good points there.

Now, if you have a 'Commie flag tacked up on the wall inside your garage, that might change things. ( I'd have to call home and ask your wife. )


I'd be tempted to stack a couple of exhaust adapters together just to see how much flow / power is affected.

I'm not sure how much noise reduction is offered by a plain spark arrestor unit so you still might need to add a muffler. Something that bills it's self as a " spark arresting muffler " would fit the bill.


Given an on road vehicle needs a spark arrestor when off road, an off road store should have something. This is exactly why I suggested that the regs be pulled. With that bit of info, you are not breaking new ground here and someone has to make an add on arrestor for small trucks.

Perhaps digging around a camping / off road forum would turn up something.

To address another post:

The issue isn't gasoline, propane or diesel fuel / spark or compression ignition. What happens is carbon builds up inside the exhaust system, breaks loose and is glowing red as it exits the exhaust pipe.

From what I know the install regs to be, the spark arrestor unit ( spark trap ) needs to be post muffler and as near to the end of exhaust as possible. A screen needs to be at the end to pipe to catch any stray carbon that got past the arrestor unit. ( As you stated )

Hah! "Now you tip your hat to this lady, son" and when I did all that hair fell out from underneath.
