Twisted Steel Header, Up-Pipe & Downpipe

Header & Downpipe

About the manufacturer

Upgrade or replace your LML’s manifolds, up-pipes, and down-pipe with this all-in-one, bolt-on kit, designed to open up your exhaust flow for maximum performance. The headers are constructed out of heavy duty gauge, mandrel-bent 304 stainless steel tubing with a .120" wall for strength and durability. The up-pipes and down-pipe are constructed out of 2" and 3" mandrel-bent 304 brush finished stainless steel tubing. Two exhaust gas temperature (EGT) ports are provided with this system. A 1/8” NPT EGT probe port is incorporated into the driver’s side manifold and a M14x1.5 port in the down pipe. This allows for easy installation of sensors, gauges or testing equipment. A CNC-machined v-band inlet flange and heavy-duty outlet flange provide a secure, leak-free seal.
