Unknown Performance Intercooler piping kits feature all aluminium construction mandrel bent with rolled beaded edges providing smooth and higher flow of boosted air.
The main purposes of replacing stock OEM intercooler piping is to increase pipe size to 2.5", remove the many bends in the stock intercooler piping and provide the shortest path with minimum piping from the intercooler to the throttle body. Also a good part of the OEM stock intercooler piping is made from soft rubber joiners which under boost collapse or "suck in" reducing flow and lost in performance.
Unknown Performance intercooler piping kits utilizes 4ply silicone joiners with t-bolt clamps for a strong seal under high boost and will give you the ultimate performance.
