Bully Dog exhaust manifolds provide a considerable upgrade from old stock manifolds, thanks to all of their notable features. Their high-flowing, state-of-the-art CAD design provides quicker turbo spool, higher power output, and more fuel economy for Class 8 engines. They feature ceramic coating inside and out to ensure engine heat is more extensively utilized to spin the turbo. This means the special metal alloy beneath the coating will absorb and radiate less heat—up to 300 degrees less coming off the manifolds.
