Keep your factory cats and upgrade your HEMI headers

Give your supported 2009-2018 Dodge/RAM 1500 a stepped Torque Series header upgrade without replacing the factory catalytic converters. These Kooks 304 stainless headers step from 1-5/8" to 1-3/4", with D-shaped ports, EGR provisions, gaskets and fitting hardware included.

A direct connection to your factory cats

The headers connect directly to the OEM catalytic converters. Heavy-duty 16-gauge stainless tubing and 3/8" stainless flanges give the upgrade a defined construction specification, while the supplied gaskets and hardware complete the header purchase.

Measured gains for this Torque Series application

Kooks measured increases over the stock manifolds of 25+ hp at 5,500 rpm and 40+ lb-ft at 4,100 rpm, at the tyres. Those are the reported results for this header application, with power and torque quoted at different engine speeds; your finished engine and calibration determine your own result.
