Flowmaster Cat Back Exhaust

for your 1999-2004 Lightning / Harley Davidson

Flowmaster American Thunder Exhaust for the 1999-2004 Supercharged SVT Lightning truck is finally here!!! This is not just a muffler. This is a complete system that is a direct bolt on with no welding required. Flowmaster spent a good amount of time developing this system. The muffler is specifically made for the Lightning truck. This is not a standard “off the shelf” muffler like those made by other manufactures. The internal pipes of this muffler are made to flow large amounts of exhaust, without the obnoxious sound. The system comes with mandrel bent tailpipes and dual 4-inch stainless steel rolled exhaust tips for a very aggressive look that is unique to the Lightning. This item is in stock and is available for immediate release.
