Description

The American Racing Headers RM158-13134300LSNC is a long tube header system designed for 2013-up Dodge Ram 1500 trucks with 8-speed transmissions. This system features 1-3/4" primaries and a 3" Y-pipe with a true 2 into 1 merge collector. It extends past the transmission cross-member, eliminating the factory wire clamp connection.

Constructed from 304 stainless steel, this header system includes 3/8" thick laser-cut flanges, hand-ported TIG welded inlets, and optimized primary tube routing. The merge collectors are equipped with scavenger spikes. This "Off-Road Race Only" system is not intended for street use and may be illegal for sale or installation nationwide under the Federal Clean Air Act.
