Replace and upgrade your undersized, restrictive stock up-pipes in your L5P Duramax with these high flow, OEM length, performance up-pipes from PPE. These direct replacements have a 46% larger flow area over stock, which results in a deeper-breathing power-plant, while maintaining the mandated Federal emissions standards of stock.
The PPE OEM-Length Up-Pipes are manufactured from 11 gauge 304 stainless steel. These new Up-Pipes include the superior PPE internally-sleeved bellows, also manufactured from 304 stainless steel. This system is engineered to take the abuse of high temperatures and high pressures, while promoting increased exhaust flow and lower EGTs. A superior product for your modern marvel.
