Sounds like a 450 Race Bike
By T. on
Love the Way the exhaust sounds on my big bore XR100 swapped XR80r, sounds like a mini 450. Gave my bike alot more midrange and top end power with the much bigger header pipe over stock. Everything is still holding up like new after 4 months of hard use. Only complaint is I wish It came with new exhaust studs and nuts to bolt it to the head. It's very loud I wouldn't recommend if you're planning on using it on a yard bike or if you have neighbors close by. Overall 4 Stars, I highly recommend if you want a racing pipe for your XR100R or XR80R.
