That pipe is going to be cherry red no matter the muffler you install. I wrapped mine and went with a heat shield which is covered in many threads on here.

My Yamaha mechanic said it was normal and perfectly fine. He strongly discouraged the heat wrap because he felt it did not allow the pipe to dissipate heat properly and could transfer excess heat into the cylinder head.

my concern is debre getting on my installed aluminium plate and fire starting .

I can see where fire would be of concern, but I would think that whatever gets on there will be small and the fire would be minimal and short lived? To me, getting that head hotter than it needs to be is more of an issue. I plan on installing a fire extinguisher anyways, actually I already have it, just waiting on the mount to come in. Last thing anyone wants to do is to stand there and watch their machine burn to the ground!!!

Somewhere on here is a thread where someone above and beyond and measured temps on the differential pre and post heat shield install. It was to say the least, a significant reduction, somewhere in the neighborhood of almost 300 degrees down to 70'ish if I recall. As soon as I get better and learning the ins and outs of these threads, I'll be able to find it again easily. Until then, my apologies for the teaser.

I bought the Benz ATV Silencer, Sound Kit, Bed Mat, and Floor Mats. They made a big differance. Nothing is going to make it sound like a Bad Boy Buggy, however who wants that crap!!! Remember it's loud in the cab but you can talk. Outside it's a lot quieter which is what you want if you hunt
