Power isn't simply created, and maximizing your engine output is not a one-and-done project. So, when you're supping up your engine, don't forget about adding a set of Gibson Performance exhaust headers. Let that engine breathe, let that engine growl, and give it Gibson power.

Gibson headers are dyno-tuned, ensuring increased performance with each set. These bad boys are engineered to create more usable horsepower and torque during low and mid-range RPMs. How do they work? Same principle as the Gibson exhausts (which go great with these headers). Allowing for the engine to more easily move exhaust allows for a lower operating temperature, which in turn allows for more air into the engine.

Gibson engineers their performance headers as direct replacements for the factory manifolds, retaining the crossover pipe and all 50 state legal emissions equipment. Gibson performance Headers are available in 3 finishes - 14ga chrome plated steel, 409 stainless steel, or ceramic coated. Gibson Exhaust also provides air injection and oxygen sensor fittings. Gibson headers are backed by a lifetime warranty.

Get a set of Gibson Performance exhaust headers. Your engine will thank you – seriously.
