Doctor Diesel USA’s new Twisted Steel header delivers an
astounding 9 hp and 10 lbs. x ft. torque while outflowing the factory exhaust
manifold. The header is constructed of 1.5” 14-gauge 409 SS tubing with a 1/2”
thick head flange to ensure a leak free seal. To eliminate dead space that can
cause turbulence and hindering flow that formed collectors are prone to
produce, a true merged collector and optimized tube lengths are used for true
pulse control technology improving flow and performance. 100% hand TIG-welded
construction ensures optimal strength and durability. The smooth curves and
increased diameter of this header helps remove restriction and keeps exhaust
gas flowing smoothly for improved performance and durability on and off the
trails. All components are supplied for a hassle-free installation with no
modifications necessary.
Mitered Collectors: Mitered collectors extend the tube length into
the flange which decreases turbulence and increases exhaust velocity. The
result is increased horsepower, torque and improved throttle response.
Tig-Welded: 100% TIG-Welded by certified craftsmen for race proven
strength and durability. TIG-Welding provides the strongest welds reducing
stress cracks.
1/2" Thick Head Flange: A 1/2" thick head flange is used
for maximum strength and durability. The flange design is identical to the head
port and is machined flat for a leak-free seal.
409 SS Construction: This header is constructed of durable CNC
mandrel bent 14-gauge 409 stainless steel tubing for maximum performance,
corrosion resistance and strength eliminating cracking.
Premium Gasket: A premium intake/exhaust flange gasket with
aluminum fire rings is provided for a leak-free seal. The gasket is port
matched for a perfect seal.
Twisted Steel Headers come with a Limited Lifetime Warranty.
