The American Thunder high performance exhaust system provides an aggressive tone both inside and outside of your Ford Mustang, Chevy Camaro, Corvette or Firebird! 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 just like the original equipment of your car. Another benefit of the American Thunder exhaust system is a total bolt-on installation that does not require any welding. The kit uses the factory hangar mounts and includes zinc-plated clamps for long durability underneath your GT, LS1 or LT1.

Features Include:

• Complete 409S Stainless Steel Cat-back kit
  
• True bolt on installation - no welding required
  
• Terrific Flowmaster American Thunder sound
  
• Uses dual 409S Stainless Steel Super 44 mufflers
  
• 2.5" mandrel bent pipes for maximum exhaust flow
