Modified Mustangs & Fords Completely Unscientific Muffler Test

Web Exclusive! - Mustang FR500S Mufflers vs. stockWhile in Birmingham celebrating the Mustang 45th we saw Ford Racing installing a lot of parts. From cold air kits to rear gears to mufflers they were busy all weekend. The most popular muffler being sold was the 5230S muffler. This is the muffler that comes stock on the FR500S Mustangs used in the Mustang Challenge for the Miller Cup series. To find out how good they sound compared to other mufflers we had Ford Racing send us a pair to give them a completely unscientific test.
