Overview
aFe BladeRunner Exhaust Manifolds
BladeRunner exhaust manifolds from aFe are made from 304 stainless steel and feature a one-piece design with reinforced ribs between each exhaust port. This increases strength and eliminates the cracking found in most stock and aftermarket units. These manifolds feature two EGT probe ports, a thick wall design for increased strength, matched ports, and a merged runner design to maximize exhaust flow. Once you've installed a BladeRunner on your ride, you'll be able to feel improved turbo spool-up times, throttle response, and decreased EGTs. For top performance, choose an exhaust manifold from aFe.
