The included aircraft-grade 304 stainless steel up-pipes feature internally sleeved bellows with an increased 2-inch inner diameter for optimized flow and reduced exhaust back-pressure. This design lowers exhaust gas temperatures (EGTs), enhances turbo spool-up, and contributes to improved fuel economy and long-term reliability. Manifold gaskets are coated with a protective molybdenum compound to ensure a secure, leak-free seal. Each up-pipe is constructed from 11-gauge, 0.120” wall stainless steel for strength and longevity.\n\u003c\/p\u003e","brand":"Pacific Performance Engineering","offers":[{"title":"Default Title","offer_id":51638003925275,"sku":"116112500","price":1349.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0962\/5757\/3147\/files\/Screenshot2026-01-19at9.45.21AM.png?v=1768841140"},{"product_id":"dhd-300-125k-oem-length-d-pipe-stainless-passenger-lb7-up-pipe-kit-2001-2004","title":"DHD 300-125K OEM Length D-Pipe Stainless Passenger LB7 Up Pipe Kit 2001-2004","description":"\u003cp\u003eUpgrade your LB7 Duramax with DHD’s full-featured OEM-fit up-pipe, delivering high performance at a fraction of the cost of a new GM unit.
