Two Brothers S1R Slip-On Exhaust 5 5 1 1
This product makes my bike feel brand new! This product is amazing sounding, it is easy to install it took about 5 minutes to put on and I was back on the road again. It makes me feel like my bike is brand new like the first time I took my bike out. It has a sound of pure power, any video of it does not do it justice. It is loud and a bit on the high side of price, but its all worth it, I love this exhaust. September 6, 2014
