Speedway Motors has developed a very cool option for chanelling exhaust gases out of an LS street rod engine: stainless steel Tru-Ram® LS1 Exhaust Manifolds. Made of high grade stainless steel, Tru-Ram® LS1 Exhaust Manifolds combine the reduced noise level and low maintenance of a cast manifold with the excellent flow characteristics and dramatic performance gains of a tube header. Tru-Ram® Manifolds are a perfect replacement for restrictive OEM LS1 manifolds or noisy, leaky tube steel headers.
Tru-Ram® LS1 Exhaust Manifolds are designed to tuck tight against the engine block, providing the ultimate in frame and steering clearance for a wide range of applications. Large 1-3/4-inch primary ports and 3-inch outlets deliver fantastic flow and horsepower gains.
Tru-Ram® LS1 Exhaust Manifolds are made from durable and corrosion-resistant 17-4 stainless steel, which delivers an extremely strong casting that polishes brighter than other forms of stainless. This cast construction is superior to tubular steel headers for minimizing noise and retaining heat, while thick flanges eliminate leaks. Tru-Ram Stainless Steel LS1 Manifolds are available beautifully polished or unpolished, and have standard three-bolt header flanges. Each pair includes gaskets and stainless steel hardware.
