Most noticeable is the subtle, but distinctly aggressive, change in exhaust note. 1-X systems are only slightly louder than your stock exhaust at idle, but they deepen to a low “growl” during acceleration.
An 1-X aftermarket system adds to your car or pick-ups appearance, with large tips and highly polished mufflers that provide a more refined, aggressive look.
An aftermarket performance exhaust can free some of the power in your engine. The 1-X system allows for a quicker, more efficient path for exhaust gases to escape. This means your engine “breathes” better, so spent fuel and air exit the combustion chambers faster. That means more fuel and air can be burned to create more power. Plus the added bonus, a boost in fuel economy.
Technically, the “downpipe” section of the exhaust system connects the headers or exhaust manifold to the catalytic converter(s). However, on a vehicle equipped with a turbocharger, an after-market downpipe can offer a significant improvement in performance.
The F1-X downpipe improves performance. 1-X downpipes are both mandrel bend and larger in diameter. They significantly reduce restrictions and make huge improvements in horsepower.
