The Ultimate Direct Replacement for MOPAR 68444858AA
Keep your 2019-2024 RAM Pickup 6.7L Cummins on the road and out of the shop. The ATS Pulse Flow Exhaust Manifold is the definitive fix for the common warping, shrinking, and cracking issues found in factory MOPAR cast-iron units.
Since 1995, ATS Diesel has led the industry in exhaust gas technology. By combining patented Pulse Flow geometry with high-grade D3 High Silica Moly (HSM) cast iron, this manifold not only outlasts the stock version but actively improves efficiency by lowering EGTs and reducing back pressure.
Key Product Benefits
Advanced Ceramic Coating: Each manifold is finished in a high-temp ceramic coating providing substrate protection up to 1600°F and environmental protection up to 2000°F. This clean black finish traps heat inside the manifold to reduce extreme under-hood temperatures while effectively preventing corrosion and rusting.
Prevent Manifold Failure: The stock MOPAR 68444858AA manifold is prone to shrinking, which often snaps studs and causes leaks. The ATS multi-piece design allows for thermal expansion without stressing the cylinder head of your 2019-2024 RAM Pickup 6.7L Cummins.
D3 HSM Material: Constructed from High Silica Moly iron, designed to withstand the extreme heat cycles of heavy towing without cracking or becoming brittle.
Lower EGTs & Better Flow: The patented internal bell mouth design smooths out exhaust pulses, increasing velocity and improving turbocharger spool-up.
Reliable Clamping: Designed to work perfectly with ATS 12.9-grade black oxide studs for maximum clamping force.
Choose the kit level that best fits your project, from a base manifold to a fully loaded installation package.

ATS LIMITED PRODUCT WARRANTY
ATS Transmission packages carry a standard THREE YEAR Warranty. There are several exceptions, so refer to the Warranty’s specific terms and conditions . All labor, shipping, or any other charges associated with the product and the product’s failure are not covered under Warranty. Labor and/or shipping charges will not be refunded under any circumstance. After the one-year anniversary date of the original purchase, there is a limited parts replacement Warranty only. Transmissions that are purchased separately outside of a transmission package / stage and are installed without an ATS torque converter carry a 1 year parts only warranty and there is no labor or shipping allowance for transmission only purchases.
In the event of a product failure, the consumer must return the defective product to ATS for inspection before a replacement is sent to the consumer. After ATS inspects the product and completes the failure analysis, the inspection officer at ATS will provide written documentation stating the condition of the product and determine, to the best of his or her ability, what caused the malfunction or complaint. Based on the findings of the inspection report, ATS will determine whether there is a valid Warranty claim. Should a consumer require immediate service, and chooses not to wait for their product to be returned to ATS for inspection, service, and potential repair or replacement, the consumer can purchase a replacement product from ATS. The consumer must pay the full current MSRP, the applicable core charge, and shipping to and from ATS’ shop. When the defective product arrives, ATS will refund the core charge and inspect the product. During inspection, ATS will assess the product for warrantable damage. If the original product has indeed failed under the terms of the original Warranty, ATS will refund the full purchase price for the replacement product only. If the product has failed due to any issue not covered under the original Warranty, ATS will assess charges to the consumer based on any parts necessary to return the product to nominal ATS standards. ATS will deduct the total cost of required parts from the replacement product’s purchase price, and the consumer will be refunded the difference (if any) between the purchase price paid for the replacement product and the cost of parts.
If the consumer can wait for their product to be returned to ATS for inspection, service, and potential repair or replacement, the consumer pays shipping to and from ATS’ shop. When the defective product arrives in Colorado, ATS will inspect the product. ATS will then assess the product for warrantable damage. If the product has failed under the terms of the original Warranty contract, ATS will repair or replace the product – at ATS’s discretion. If the product has failed due to any issue not covered under the original Warranty, ATS will assess charges to the consumer based on any parts necessary to return the product to nominal ATS standards. ATS will bill the consumer for the total cost of parts required for repair of the product, and shipping to and from Colorado, prior to the repaired/replaced product being sent to the consumer.
ATS Manual Transmissions Warranty
This section incorporates Section 2, entitled “In the Event of a Failure.” ATS manual transmissions carry a 1-year/12,000 mile Warranty. ATS will not pay for any fluids replaced in the event of a transmission failure. There is no labor or freight warranty coverage on standard transmissions. Manual transmission shafts and gears are not covered by this Warranty on any transmission due to the capability of certain situations to cause stress-loads beyond the structural ability of the shaft or gear.
