Cracks are finicky. They look great on the Liberty Bell, but they’re not so hot on your plumber. Of course, cracks under the hood are more than just an eyesore—they put your rig out of commission. Since stock exhaust manifolds are notorious for cracking, swap yours out with a heavy-duty aFe BladeRunner Exhaust Manifold.
Nails can only dream of being as tough as your aFe Exhaust Manifold. Custom built from either ductile iron or 304 stainless, aFe equips each manifold with a beefy .25” thick flange to withstand the harshest conditions without warping, flexing or cracking. Plus, a reinforced rib runs the length of your aFe BladeRunner for added structural strength. No matter how hard you push your powerplant, this manifold has the backbone to survive unscathed.
More than just muscular, your aFe BladeRunner Exhaust Manifold also boasts hotter performance. Built with matched ports and a unique merged runner, it cranks up your exhaust flow between 23% and 50% (depending on your rig). Faster turbo spool up, quicker throttle response and blistering power—they all come standard with your aFe Blade Runner Exhaust Manifold. And, it’s covered by a 2-year warranty.
