Flowmaster – Cat-back System ‘87- ‘93 Ford Mustang GT, 5.0L, AMERICAN THUNDER® SYSTEM, DOR Dual Out

The 1987-‘93 Ford Mustang GT is a favorite of performance fans and helped make Flowmaster a household name. Now owners of these great muscle cars have the choice of standard aluminized kit construction or Flowmaster’s new 409S® stainless steel kit (PN817116). Both deliver that great Flowmaster signature sound, increased performance and improved throttle response.  Featuring Super 44™ mufflers, this American Thunder system provides an aggressive tone both inside and outside the vehicle. The new kit also incorporates all of the benefits of the standard aluminized steel kit including standard turndown exhaust exits just ahead of the rear valance as

in the OE configuration. A total bolt on installation that does not require welding, the kit uses the factory hangar mounts and includes zinc-plated clamps for long durability.

• True bolt on installation – no welding required

• Terrific Flowmaster American Thunder® sound

• Uses 409S® Stainless Steel Super 44™ mufflers

• 2.50” mandrel bent tubing for maximum exhaust flow
