These full featured OEM length up pipes are an excellent value! These are brand new and include all the high flow, high quality features your looking for at half of new GM LB7 up-pipes.
DHD has taken OEM replacement to a new level. This stock replacement up pipe set allows 53% greater flow than stock and is a direct bolt-on to your factory manifolds. Unlike factory parts, our up pipe is manufactured from 11 gauge 304 stainless steel and includes DHD's HD 304 stainless steel, internally-sleeved bellow that can take the abuse of high temperature and high pressures. Each up pipe outweighs the competition by nearly a pound and features internal and external flange TIG welds!
