Good purchase

Noticeable power gains in the low to mid range power. Have it on 2015 Honda crf450. Do all single track trail riding and hillclimbs. Happy with the purchase.

Q: Are these supposed to come with reducers or clamps to go on the stock header? I received this slip on and attempted to install on my stock header but realized I needed some other hardware.
