Quick install.
Works awesome! Previous owner did mx only. This saved my ears from bleeding and made it legal for off-road at the same time.

Good spark arrestor. Would not recommend as a silencer.
The product fit and went in place well . Fine product if you just need a spark arrestor. Did not quiet the pipe at all. The muffler stayed at 102 dB.

Quieter
Quiets the exhaust a little bit, doesn't seem to affect power in any way. Doesn't have the cross piece like the spark arrestor that comes with the factory 4.1rct.

Does the job!
Fit great and very easy to install. Had to knock the value since they know most people are going to have to buy them separately.

Was a tight fit, but at least it won't fall out!

Does this spare arrestor can be fit in the original 2016 YZ450fx muffler?
A shopper on Feb 16, 2017
BEST ANSWER: Most likely not. Maybe with some modifications but depends on the diameter of the opening on your muffler. It is designed specifically to work with the fmf 4.1 rct muffler
will this fit in a stock exhaust for a 2008 KTM 450sxf? Thanks!
Brian R on Jun 23, 2017
BEST ANSWER: Nope, it only fits the FMF Factory 4.1 RCT mufflers. Your only option for a stock muffler is promoto billet or lexx if they make an end cap for your model.
Does this come with the decal stating that the insert is a spark arrestor?
Sam G on Mar 28, 2017
BEST ANSWER: No it has been a while but I believe it does not.
What are the dimensions. i.e. length and OD?
Joseph M on Sep 8, 2017
BEST ANSWER: The overall length including the screen is 8 inches. The tube is 1.5" diameter. The mounting ring is 1.625 inches diameter and 0.625" wide. Fit perfectly in my Titanium 4.1.
does the rct 94db spark arrestor come with the retaining clip to hold it in the exhaust?
Allen M on Jan 25, 2017
BEST ANSWER: Yes, it does.
