BladeRunner Ductile Iron Exhaust Manifold (46-40012) 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.

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.

aFe (Advanced Flow Engineering, Inc.) manufactures performance products for late model cars, light trucks and SUVs. The company was founded in 1999 with an initial concentration on high performance air filters. Since then, the company product line has broadened to include cold air intakes, fluid filters, exhaust systems, intake manifolds, intercoolers, programmers, differential covers, transmission pans and throttle body spacers. The team of engineers, machinists, production and sales people at aFe have many years of experience in their respective positions, and together work to ensure they produce the best automotive products on the market.

Terrible sound quality and bass
Style: X5206 with Two Woofers
Sounds cheap, didn’t come with a charger, and the bass does not vibrate at all, so I bought got a jbl 110 the next day. The jbl is a thousand times better, the bass blew me away, and the sound is very high quality. Don’t waste your time and money on it get a jbl

Turn me up turbo
Style: X3206 with One Woofer
I bought this for my performances assuming well of the brand (I’m a musician). My biggest complaint is that I wish it were louder. There have been performances where they’ve asked me to turn the volume up and surely enough it’s already at its loudest volume 🥴. The battery life is pretty good, it’s never died on me and I’ve had 4hr gigs before. The light is also a nice touch (and can turn on and off per your request of hitting a button). It makes a sound when you turn it on and off which can also be muted if you can catch it in time. Pretty easy for me to carry from place to place. Im not sure I’d recommend it to a musician but depending on what it is you need it for- it’s truly not bad. For the price it’s pretty average and until I can invest in a louder option, it gets the job done pretty okay.

Not bad
Style: X5206 with Two Woofers
A good speaker, wish it connect to my tv without an audio cord. But the sound is not bad. It’s good for the price.
