Flowmaster 17220 Chevrolet GMC 6.5 Turbocharger Downpipe

Designed to replace the factory flattened and restrictive original turbo downpipe coming off the turbocharger outlet and the factory installed crossover pipe. The Turbo downpipe is constructed from large 3.00-inch mandrel-bent 16 gauge aluminized steel for maximum flow and includes a factory style turbo flange for a direct-fit. The crossover pipe is constructed from 2.50-inch mandrel-bent aluminized steel and has factory style 3-bolt flanges for a trouble free install and precise fit. The kit includes all necessary hardware and instructions for an easy installation you can do at home.
