    Product Details

    BladeRunner Exhaust Manifold by aFe®. Replace the exhaust manifold on your Dodge diesel with the BladeRunner manifold. It was created to address a cracking problem with the stock manifold, but it's so far advanced compared to the stock unit, you should replace your OEM manifold even if there's nothing wrong with it. The BladeRunner manifold will not only last far longer, it will improve performance and lower exhaust gas temperatures.

    Installation

    aFe designed the BladeRunner exhaust manifold for the 5.9L Dodge Diesel engine primarily to address a common problem with the factory manifold, which has a tendency to crack over time. But the end result is so superior to the original unit that it should be installed for the performance gain alone.

    To solve the durability problem, aFe casts the BladeRunner from 304 stainless steel and makes the walls of the manifold thicker, 0.25" versus the stock 0.15". A reinforcing rib runs along the flange for additional strength. While they were at it, the engineers at aFe merged the exhaust runners for maximum flow, as much as 23% more than stock. The manifold features 2 EGT (Exhaust Gas Temperature) probe ports, so the EGT can be measured on each bank separately. The end result is increased exhaust flow that results in faster turbo spool-up, reduced EGTs, increased performance and improved throttle response.

    The BladeRunner Exhaust Manifold comes complete with all mounting hardware and detailed installation instructions. It's backed by limited 2-year warranty.

    Good Fit, Great Quality
    I've been hunting for headers for my '21 ram and finally decided on these. Honestly I was worried they wouldn't fit quite right but they bolted up perfectly. I swapped out the supplied bolts for some heavy-duty ones just for peace of mind. aFe makes solid stuff and the price is pretty reasonable for what you get.

    aFe Is Junk!! TRUCKiD Is Great.
    Afe makes over priced junk. TRUCKiD is a great company that does as they say they will. Afe will not honor their warranty. I stress do not buy headers or any of their other products. Shorty header was installed for 6 months before cracking. Two months later still no replacement part and no communication.
