Won't fit Carbon Fiber unit

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.

Noticeable noise reduction

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.

Older Models Not Excepted

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's a Spark Arrestor

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.

Should have been included in the first place!

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!

A: The Yoshimura Spark Arrestors are model-specific, and made only to fit the exact Yoshimura mufflers intended for each particular motorcycle. The dimensions vary, depending on which motorcycle and muffler the spark arrestor is intended.
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.

A: No, this insert is for Yoshimura exhaust's only. You would need to shop in the OEM section to find the original insert for the factory exhaust.
Q: Looking for replacement parts for the OEM muffler that will interchange. Somebody took the guts (baffles etc.) out of the muffler before I bought it and it is too loud. It just has the open muffler can. 2006 Yamaha TTR90

A: This piece is not for the stock exhaust. The onyl parts that would fit in to the stock exhaust would be the OEM parts which Yamaha does not offer. You would have to buy a whole new exhaust system.
Q: Does this fit a honda 400ex stock exhaust?

It says it is an exact fit for my stock exhaust but I see in these questions that it doesn't fit many bikes that people asked about. So is it a match or no?
