Suncent® Exhaust Shorty Header for 1969 - 1982 Chevrolet Corvette Small Block 5.7L V8 Fitment: 1969-1982 Chevrolet CorvetteOnly Fit Small Block 5.7L V8 Engine Why Choose Exhaust Headers Over Stock Exhaust Manifolds? Compared to stock exhaust manifolds, the Exhaust Header is made from lighter stainless steel and features nearly identical pipe lengths connecting each cylinder, ensuring even exhaust pulses. This equal-length design effectively prevents exhaust gases from different cylinders from colliding, reducing backpressure and enhancing both intake and exhaust efficiency. As a result, the Exhaust Header is the ideal choice for optimizing engine efficiency and performance. The Benefit of a Exhaust Header: 1. Unlock Greater horsepower with Enhanced Torque The exhaust header can boost horsepower by 8% to 12% and torque by 6% to 10% , making it a must-have choice for those pursuing optimal performance. 2. Optimize The Vehicle Weight Distribution The exhaust header, made of lightweight, thin high-quality stainless steel, reduces weight by 10-30 pounds , bringing the front-to-rear weight distribution closer to an ideal 50:50 , enhancing acceleration, handling, and braking performance. 3. Transform Your Vehicle’s Sound An exhaust header enhances the exhaust note, producing a deep, commanding tone at low RPMs and a thrilling, passionate roar at high RPMs. 4. Boost Fuel Economy With Optimized Exhaust Flow For drivers avoiding extreme performance, this exhaust header lifts fuel efficiency by 3% in L4/L6 and 5% in V6/V8 models, ideal for fuel savings.

We must be honest; due to space constraints within the vehicle, it's challenging to fit complex piping, so it cannot be 100% equal in length, as compatibility comes first. What is the difference between a long tube header and a short header? Short header add more torque at low and medium speeds. Long Tube header are the idea choice for a balance of performance and noise at high speeds. Read More
