this spark arrester works great! it takes a little to install however the quality is worth it ! good product!
Bummers, doesn't fit my Yoshi Carbon Fiber can. Wish they had mentioned that. Besides that painful discovery, unit looks solid, simple and built to last with ease of installaion.
Installed on a 05 LTZ 400/455 with a Yosh RS3 system. I purchased this insert for the spark arrestor and the noise reduction was a huge bonus. I haven't measured the sound, but it’s a very noticeable drop. Installed in less than 2 minutes and works great. I primarily ride trails, so I'm not looking for the high end, get every ounce of power performance - my quad ran great. In short, this works as designed and described.
BE CAREFUL!!! I recently bought this yoshimura spark arrestor. I have a 2001 model of a yoshimura exhaust. Upon opening the endcap of my pipe i discovered the spark arrestor didn't fit. If you have an older model yoshimura exhaust don't buy this spark arrestor unless you're ready to modify.
It does make your yoshi pipe quieter and obviously is a spark arrestor. I didn't really notice a power loss which was surprising for a quiet core.
It fits perfect and is easy to install; what more do you want out of spark arrestor/quiet core?
It is a spark arrestor. Pretty quiet, so quiet I took it out. Works good if you want quiet exhaust.
Forget about the spark arrestor that comes with the RS3 exhaust, it's opening is smaller than a finger. This spark arrestor will open up your exhaust without catching anyone's attention and sounds great. This should have been the spark arrestor included with this pipe!
If you correctly profile your motorcycle, including the model year, we will send you the specific unit to precisely fit your bike with the Yoshimura muffler.
