Performance and off-road mid-pipes for your SVT Lightning are designed to reduce restriction with a combination of different techniques. Check out our selection of Bassani Mid-Pipes for your Ford Lightning. Most aftermarket mid-pipes are mandrel bend to maximize the diameter of the exhaust tubing at the turns. Some of the aftermarket mid-pipes we carry for the F150 Lightning feature high flow catalytic converters that will improve exhaust flow and sound while keeping your SVT pickup legal in most, if not all, states. Finally there is the off-road mid-pipe which gets it's name from the fact that it does not have catalytic converters and therefore is not designed not pass emissions testing making it legal for "off-road" and racing applications only.
