A direct fit replacement performance manifold for 2003-07 5.9 Cummins in Dodge Pickups.
This is a T-3 flange which is the same as the stock turbo.
Our design is based on Computational Fluid Dynamic (CFD) Testing, which will results in quicker turbo spool-up, and improves flow characteristics over 23% compared to the factory manifold. This manifold is ceramic paint coated to withstand high temperatures.
** Legal for installation and street use in California, California E.O. Exemption**
With our multi-piece divided T3-flange design our manifolds can expand and contract with heat, eliminating warping and cracking.
Lower's EGT on the rear ports by as much as 200 degrees F. Balances the exhaust temps across the cylinders much better then the factory manifold.
The factory heat shield will be removed for installation as it is unnecessary. See the instructions included in the box for more information.

Good quality part fast shipping
Good lookin manifold. Its nice that it comes with tapped ports for a pyrometer. Unable to monitor EGTs at the moment. Only issue I had with the manifold is the bottom stud on #5. Incredibly tight clearances between the manifold and nut making it near impossible to get a wrench or socket on it - i did though.... Other than that fitment and looks are nice!
I've had this manifold for a few months and finally got around to installing it. Not a bad job but do yourself a favor and get a cap screw for the bottom hole on the number 5 cylinder. My truck is running like she is new again. Smoother acceleration. Faster spool up on the turbo. I put a straight edge on it before I installed it and it was perfect. Installation can be a pain but it's well worth it to me. Hoping to put the Artic Air intake on it soon if they get them back in stock.
Very happy with the product I received. It was shipped quickly and great customer service.
This was shipped ridiculously fast!!! So impressed! Thank you!
Great quality product came shipped well packaged and fast delivery And these things look amazing. Well built and happy to support a local Utah business!!!
picked up my new manifold and installed it over the weekend. I love it! Incredible difference. Silenced all the extra noise under my hood, turbo spools faster, hits hard and sounds amazing. I never have heard my turbo spool so loud. Throttle response is so much better. GREAT PRODUCT! worth the money and drive I did to pick it up!
Great manifold for a great price. Shipped out same day I ordered. Hardest part of install was getting my old one out.
Very nice manifold. Bigger than stock. Just got done installing it. Pretty good difference over stock and sounds much better by giving the exhaust a lower tone.
