In the Dynomax [(734) 384-7806; www.dynomax.com] trailer, we found a New-Edge Cobra up on the lift featuring the company's 3-inch exhaust system for IRS-equipped Mustangs. Oh wait, that's not an actual car, it was a sticker on the ceiling of the trailer, but the exhaust was real. Aside from the exhaust display, DynoMax also had a listening station so you could hear one of the company's exhaust systems on a variety of vehicles, including a Mustang.
