The newest release in the Kooks Torque Series comes in the form of Part# 35101110, headers for 2009-2018 RAM 1500 Trucks with the 5.7L HEMI. These headers are made in high quality 304 grade stainless steel with 3/8” thick flanges, heavy duty 16 Ga. primary tubes that step from 1-5/8” to 1-3/4”, our patented scavenging spikes and one-piece collectors. The outlet of the headers features 3/8” thick 2-bolt flanges and formed balls to connect to the OEM exhaust allowing for a direct bolt-on installation. The kit will include installation hardware, and required gaskets.
When bolted onto the 5.7L HEMI, the Torque Series headers flatten the torque curve to produce an increase of 25+ H.P. at 5500 RPM and 40+ lb-ft of Torque at 4100 RPM over the stock manifolds when measured at the tire. The peak numbers show an increase close to 25+ H.P. and 15+ lb-ft of Torque.
