Replace the lightweight, leak-prone, 1 5/8" OEM up pipes with these heavy-duty 11 gauge 2" Stainless up pipe kit. HD Stainless Bellows that will not crack and leak like OEM. Increase Turbo spool-up and decrease EGTs. This kit is used with twin turbo applications and factory exhaust manifolds or WCFab Duramax Billet Exhaust Manifolds (WCF100363); they WILL NOT clear a conventional downpipe routed behind the engine. Both sides are nearly symmetrical, with no indents for a conventional downpipe to clear.


NOTE: These up pipes WILL NOT CLEAR a standard downpipe routing behind the engine.

For Twin Turbo Applications ONLY!
