This pipe replaces the factory drivers side intercooler pipe on the L5P Duramax's with a solid one piece 3" unit. Remove your 2.5" factory intercooler pipe that has 3 silicone boots and enjoy the extra reliability, the added looks, and the option to have us coat the pipe any color you'd like doesn't hurt either! As always, these are made 100% in the USA with in house fabrication and powder coating.
