Turbo Up Pipes

Eliminate power-robbing pre-turbo exhaust leaks, lower exhaust gas temperatures (EGTs), and improve spool response on your 2001–2004 Chevy Silverado or GMC Sierra 2500HD/3500HD with our selection of LB7 Duramax turbo up-pipes. Over years of thermal cycling, vibration, and heavy towing stress, the factory thin-wall OEM up-pipe expansion bellows inevitably crack, soot up the back of the engine block, and leak drive pressure before it can reach the turbocharger. Upgrading to heavy-duty stainless steel up-pipes featuring internally sleeved, multi-layer flex bellows and larger-diameter tubing ensures leak-free reliability, increased exhaust flow velocity, and faster boost onset. We carry driver-side, passenger-side, and complete high-flow up-pipe kits with heavy-duty multi-layer steel (MLS) gaskets from top industry brands like PPE, BD Diesel, and MBRP.
