AFE BladeRunner Ductile Iron Exhaust Manifold 98.5-02 Dodge 5.9L CumminsThis BladeRunner manifold is available both in a ported and non ported version. While both outflow the factory manifold by 50%, the ported version has finer finish work done to the ports to further reduce any potential turbulence that can arise from non finished castings.

This BladeRunner manifold is available both in a ported and non-ported version. While both outflow the factory manifold by 50%, the ported version has finer finish work done to the ports to further reduce any potential turbulence that can arise from non-finished castings.

If you're the owner of a 98.5-02 Cummins, you're probably aware that the stock manifolds are known for cracking on the underside. Until now, the cure has been to install a multiple piece manifold that allows for expansion/contraction joints. Unfortunately, these joints are also known for leaking. AFE has solved this problem with their new BladeRunner manifold. In recent testing, this ductile iron manifold outflowed the factory exhaust manifold by 50%, improving performance and throttle response.

The thick wall flange design also increases strength, eliminating warping and cracking. The matched ports and a merged runner design reduces backpressure, which assists in maximizing exhaust flow to reduce EGT's.

One-Piece Construction - This manifold is constructed out of durable cast ductile iron with a reinforcing rib for maximum strength along the flange and ultra-thick wall flange at the port.

Multiple Auxiliary Ports - Two EGT (exhaust gas temperature) probe ports are supplied for easy installation of gauges or testing equipment.

Hassle-Free Installation - All necessary hardware is included for a hassle-free installation (Non-Ported version does NOT include gaskets, however, the Ported version DOES include gaskets).

Size: 10-11, Color: Cable Knit Black
Comfy but cheaply made. I bought these for the price and expected them to be not the best quality but they are even less than I expected. Please also note that they run small. I got a 10-11 since I wear 11 shoe and Amazon recommended this size. I think a size larger would have been better. Not worth returning though. I’ll just wear them this winter if they last that long and get a better brand next time.

Best Muclucs I've every owned....GREAT PRICE!
These things are so comfortable and warm. I sleep with them on because I like to have my feet out of the covers. Not too warm...just right. Great quality and fit with a non-slip leather-like sole. I'll keep ordering these ahead of time to make sure I'll always have a fresh pair when I wear them out. I wear them EVERY NIGHT and keep them on all morning. Life-changer! The BEST EVER!!
