Long-Tube Headers
Do long tube headers increase horsepower? Yes, long tube headers increase horsepower. If your state allows long tubes, this is a great investment in reliable performance.
Do long tube headers improve gas mileage? Yes, from a technical standpoint. In most cases, fuel mileage will increase when you add long tube headers. The problem that Accesspeed customers have is keeping their foot out of the throttle because headers add so much horsepower.
Are long tube headers legal in my state? If your state requires the OEM catalytic converters to remain stock, and in their original location, long tube headers are most likely illegal in your state, as these headers require modification or removal of the OEM cats.
