HSP Diesel S300 Down Pipe for 2001-2016 GM Duramax 6.6L LB7/LLY/LBZ/LMM/LML
The HSP S300 Single Kit Downpipe is constructed from 3'' stainless steel and is built to last. Each downpipe is built in quality fixtures to ensure proper fitment. Our design allows extra clearance for aftermarket up-pipes. This downpipe comes standard with a Borg Warner marmon flange turbo connection and v-banded factory front-pipe exhaust connection. This downpipe allows great fire wall clearance and can be made to work with the factory transmission dipstick tube, but our HSP Dipstick tube will provide the necessary room for a simple install.
Note: This product is specified for HSP's S300 install kit, however, it may work with other aftermarket applications depending on pedestal height. HSP cannot guarantee proper fitment with other manufacturers components.
