Product Details

The Flowmaster Outlaw Extreme Cat-Back Exhaust System delivers maximum sound and performance for enthusiasts seeking an aggressive exhaust note. This system features a 3-inch race-proven Outlaw muffler paired with a single dump-style turndown exit under the bed, creating a deep, powerful tone that demands attention both inside and outside the vehicle.

Key Features:

  • Constructed from durable 409 stainless steel with mandrel-bent tubing for maximum exhaust flow and longevity
  • 3-inch diameter tubing throughout the entire system for optimal performance gains
  • Lightweight Outlaw muffler technology that produces more power than open headers while maintaining a controlled aggressive tone
  • Uses factory hanger locations for quick and easy installation
  • Installation can be completed in less than an hour with included hardware and detailed instructions
  • Single dump-style exit provides distinctive appearance and maximum sound output
  • Backed by Flowmaster's lifetime limited warranty on stainless steel exhaust systems

The Outlaw Extreme series is race-proven and the perfect choice for race tracks requiring mufflers but without dB restrictions. This system is designed for drivers who want extreme sound levels combined with dyno-proven performance improvements. This part does not affect vehicle emissions and is legal for sale on emissions controlled vehicles, non-emissions controlled vehicles, and racing use only vehicles.

okay

Got my exhaust fairly quick and they were easy to order through

Easy shopping The single item I received is not approved for use with gasoline. That should have made it clear in the description of the item. Now, I cannot use it.

Love item just wish it came with instructions.

Very good give you 5 stars

Easy to order!

Nice! Just wish you had PayPal.
