Who makes the HD exhaust
The mufflers flow well up to 450 horsepower. In my humble opinion there is no reason to change them unless you want something louder (read drones at hwy speeds) and then you lose bottom end power.

I wish the muffs were louder. When I first bought the truck and was driving it home, I pulled into a Harley dealership right outside Minneapolis and literally cleared the floor of the shoppers and the people working inside. There were about 30 bikers out there admiring the vehicle and they asked if I would start it back up so they could hear the "supposed" Harley rumble to the new truck that had been advertised.

Needless to say, they were disappointed!

I'm not changing the mufflers, though, because the engine is tuned around them.

Hi... I believe they are a Ford made product and F.Y.I. the HD and Lightning exhausts are the same... John from NC

FYI
The mufflers are made for Ford by Tennaco(I'm not sure on the spelling).
