When it comes time to replace the intermediate pipe on your 2001-2007 GM 6.6L Duramax (157.5" Wheelbase), use high-quality components like the AP Exhaust 48668 Replacement Intermediate Pipe. AP Exhaust constructs their pipes from 100% aluminized steel and make sure all brackets, flanges, and shielding are in their original locations. They even re-aluminize the weld seam to increase durability and corrosion resistance.
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.
