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, which results in a deeper-breathing power-plant, while maintaining the mandated Federal emissions standards of stock.
The Length Up-Pipes are manufactured from stainless steel. These new Up-Pipes include the superior internally-sleeved bellows, also manufactured from stainless steel.
This system is engineered to take the abuse of high temperatures and high pressures, while promoting increased exhaust flow and lower EGTs.

Great quality for the money. Welds are great and packaging was great. Shipping caused the outer box to be quite damaged but the product was perfect. I would order again in a heartbeat! No brainer!!
