I just installed the silent core insert on my 2018 TRX250X with an HMF Perfoemance exhaust and it does fit and work. The decibel level decrease is very substantial at idle but maybe 4-5db quieter when I go full throttle. I do have a bigger jet kit and air box lid off. I would give it 4 out of 5 stars, good product!

We're happy with our purchase & power. We recently put one on a 2005 Yamaha 450yfz quad.

The sound is nothing short of amazing. I would highly recommend this for anyone looking for that deep throaty tone for their quad.

Replaced old torn spark aresster with this one. Worked perfect. No issues fit just like old one.
