The first time I put the FMF Factory 4.1 RCT aluminum silencer with carbon end cap on my bike, it instantly changed the whole vibe. It doesnt even feel like a normal dirt bike anymore. The sound is perfect deep, sharp FMF tone that makes every throttle hit feel serious, not just loud for no reason. Fitment is super clean too, like it was made for the bike. Only thing is these carbureted 2010 KX250Fs run lean, so it needed jets but the pipe came with cash back, so it was basically a win. Now it runs cleaner, pulls better, and honestly just feels way more dialed every time I ride. For the older 2010 kx250f riders 42 pilot 188 main dialed!

P3 always makes the best products. These are so much better then the stock metal ones.

It's fine and it works. Stopped my pants from melting in the pipe. It busted on the first decent drop I had. Debating on if I'm going to replace it or find something else

Seems legit. Worked fine. Plenty for my FMF silencer + about 25% extra

Repacked a FMF QuietCore 4 on my new to me CRF450x. Worked well, good quality, good sound and power.
