Tru-Ram Big Block Chevy Exhaust Manifolds

Great News! Speedway Motors has expanded its line of popular Tru-Ram exhaust manifolds to include big block Chevy V8s!

Designed and engineered with direct oversight from “Speedy” Bill Smith, Tru-Ram Big Block Chevy Manifolds are the most sophisticated and attractive big block Chevy exhaust enhancers to be developed in decades. Manufactured from high-grade stainless steel, these manifolds give performance enthusiasts a superior alternative to junk cast iron manifolds or noisy, leak-prone tube headers. They tuck tighter against the block than other header designs, allowing much more room for frame and steering clearance. Large, smooth 1-7/8-inch primary ports, combined with 3-inch outlets, result in fantastic flow characteristics and horsepower gains.

Tru-Ram Big Block Chevy Exhaust Manifolds are made from tough 17-4 stainless steel, which delivers a strong casting that polishes to an extremely brilliant luster, in addition to resisting corrosion. The cast stainless construction is much better at minimizing noise and retaining heat than tube-style headers. The extra-thick manifold flanges not only eliminate leaks, they also allow the manifolds to be port-matched to the gaskets and cylinder heads if desired. Manifolds are available highly polished or unpolished, and have standard three-bolt header flanges. Gaskets and stainless steel hardware are included with each pair.

Tru-Ram LS1 Exhaust Manifolds

The GM LS1 V8 is a marvel of modern performance engineering. Why would you want to equip yours with headers based on a tired, old tube steel design?

Speedway Motors has developed a better option: 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.
