You may not know it, but the factory driver’s side exhaust manifold is pinched down to allow for steering shaft clearance, which actually isn’t required. As a result, this manifold only flows 80% compared to the passenger side. Further, the factory uppipes have proven to crack when subjected to higher than normal EGT's (Exhaust Gas Temperatures). In order to solve these issues, we offer numerous kits from the best in the business for improved performance, lower temperatures, and better reliability.
As always, if you have any questions about which product is right for you and your truck, do not hesitate to give us a call or send an e-mail to
