Feature

Upgrade the L5P to achieve higher-flow by bolting on PPE OEM-Length Replacement High-Flow Up-Pipes. These direct replacements have a 46% larger flow area over stock, resulting in a deeper-breathing power-plant, while maintaining Federal emissions standards. Manufactured from stainless steel, these Up-Pipes include superior internally-sleeved bellows, also made from stainless steel. Engineered to withstand high temperatures and pressures, they promote increased exhaust flow and lower EGTs.
