Performance Exhaust Manifolds
Does an aftermarket exhaust manifold improve performance or fuel economy?
The aftermarket exhaust manifolds offered by Accesspeed are designed to increase power, acceleration, and fuel efficiency.
Why buy a performance exhaust manifold when I can buy headers?
While headers offer more performance, horsepower, and fuel economy than exhaust manifolds, many headers are not 50-state emissions legal. The performance exhaust manifolds offered by Accesspeed are all CARB-approved with 50-state EO# ratings, and they do provide increased power and fuel economy.
