High Flow Bundle Kit Stage 3 for 2006-2007 Duramax LBZ Gloss White

The Stage 3 upgrade for the 2006-2007 LBZ 6.6L Duramax equipped Chevrolet Silverado or GMC Sierra 2500 / 3500 HD truck combines Wehrli's popular Stage 2 High Flow Bundle with a 3" Stainless Steel Down Pipe. This kit aims to increase air and exhaust flow for the turbo and engine, improving efficiency, throttle response, and turbo spool up. It replaces restrictive factory plastic parts with a high-flow fabricated intake pipe, intake horn, and air box enclosure with a dry filter assembly. The kit features a 4.8" turbo intake horn, 3" diameter 1-piece Driver (Hot) Side and 3.5" diameter Passenger (Cold) Side LBZ Intercooler Pipes, and a 3" Y-Bridge Kit. The Y-bridge is a bolt-together design, replacing the OEM slip-fit style which is prone to blowing apart under boost. The kit also includes silicone boots, stainless steel T-bolt clamps, o-rings, an intercooler outlet clip, and installation hardware. It is compatible with stock trucks and requires no tuning. Available in various custom powder coat colors.
