Like the overall performance it gave my truck. Helps keep the exhaust temps down.

Great kit, just needs a bit more research done on the pipe. Pipe rubs and starts rattling against the power steering metal hose couplings, even after several adjustments , problem still exists. I ended up putting a rubber pad on the tubing and zip tieing it in place before the power steering metal hose put a hole in the boost pipe!!
