Pull the plug on the competition with these new Terminators™. Flowtech has just made this leading performance muffler available for the first time for the 2005-2010 Mustang GT with the 4.6L V8. This high flow muffler set bolts right into the Mustang and with their cool black finish will keep this pony riding in style. These mufflers are a direct "bolt-on" and include welded rods and clamps for a direct fit to the factory hangers.
