I just ordered this exhaust for my kfx450r, it was at my door in 3 days, and took me about 10 minutes to install, super easy. Instantly after installing this pipe, I noticed the gain in bottom end power, it is definitely more snappy. I would recommend this exhaust to anyone. Keep in mind though, it is super loud.Read All Reviews

I spent a good week reviewing website reviews, watching You Tube videos, talking to dealers, etc. There are several options and manufacturers dealing with after market exhaust. The FMF Power Core 4 is absolutely AWESOME. The videos do not do justice to the sound this thing puts out! It went from sounding like a kitten to an angry lion in about 20 minutes of EASY installation. However, don't expect this to totally give you balls to the wall power. It did increase the performance somewhat and I am very pleased. The immediate change was just the awesome sound and rumble this thing puts out. My TTR is now as loud, or louder, than my brother's YZ! Highly recommended!Read All Reviews

Good exhaust for the price and nice to have another exhaust option on the market. Not the best sounding out there but does add a little noise with the quiet core removed, as well as a little low end power on my yz450f. Does have some rubbing issues on the tire and is very long which makes the bike look a little dated over the factory "shorty" silencer. Good for the money but if I could do it over I would probably save a little longer and go for an FMF.Read All Reviews
