If you're looking for a quality replacement intermediate pipe with OE fit for your 2001-2007 GM 6.6L Duramax (143.5" Wheelbase), turn to the AP Exhaust 48681 Replacement Intermediate Pipe. AP Exhaust makes sure all brackets, flanges, and shielding are in their original locations and constructs their pipes from 100% aluminized steel.
Note: The OE exhaust system was a welded assembly. If your truck is still equipped with the factory exhaust, you may have to replace other components. Please confirm before ordering.
