I got to say, after installing a handful of Welter Performance systems, the Thermal R&D systems are seriously lacking in QA and quality overall. The main run of pipes are butt fitted vs slip fit. Portions of the exhaust are smaller than 2". Alignment on the touring version (Lower rear exit) is a joke. There really isn't a lot of wiggle room to adjust it since the rear section is attached via rubber hangers. Neither version was truly above frame as both installs had different places exposed under the frame. If you're in the market for a rear exhaust... my opinion, pay the premium for a better manufactured system. While you are at it, snag a 2.5" exhaust incase you decide to boost.
Oh, and if you are not switching from a stock exhaust to this system, be sure you have enough springs (6 total) Polaris part number: 7043726 and an exhaust seal Polaris part number: 3610211
