In 2011, GM finally corrected the pinched-down drivers side exhaust manifold that has plagued the previous Duramax's for years. However, as with all things factory, there is always room for improvement. We offer upgraded exhaust manifolds as well as uppipe kits that are designed to significantly outflow the factory system, as well as discourage cracking, which has shown to be an issue on the factory uppipes when they are subjected to excessive exhaust gas temperatures (EGT's).
