Wehrli Custom High Flow Bundle Kit Stage 3
SKU: 100418-GM
Moderate — 2–4 hours
Overview
The 3.5-inch passenger side pipe features a CNC machined flange with a double o-ring seal and an upgraded silicone boot to withstand higher boost pressures, improving reliability and preventing leaks. The exhaust side includes a 3.5-inch downpipe that replaces the restrictive factory crushed part for better flow. This downpipe is black ceramic coated and heat-wrapped for thermal efficiency, connecting to the DOC outlet flange and mating with the OEM exhaust system's front pipe, including bungs for OEM sensors. The full assembly is finished in custom powder coat colors.

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.
Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
