since my quad didnt have the rubber pipe mounts when i bought it, and one of the mount bolts was seized in the frame, i had to make my own pipe brackets to bolt it to the frame. the mid pipe comes a bit close to the frame right where it connects to the silencer, but the silencer bolted up nicely. and yea it does look like the welds were hammered down or done better than some ive seen. only real complaint i have is where the silencer couples to the mid pipe is a bit loose.
