Product Details

The Flowmaster 818138 Outlaw Extreme Cat-Back Exhaust System delivers maximum performance and an aggressive exhaust note for truck enthusiasts who demand the loudest sound possible. Engineered with Flowmaster's signature Outlaw series muffler technology, this system provides a deep, throaty rumble both inside the cabin and outside the vehicle while maximizing exhaust flow for improved horsepower and torque.

Key Features:

  • Outlaw series muffler produces an extremely aggressive, race-inspired sound level
  • 3.00-inch mandrel bent tubing constructed from 16-gauge 409 stainless steel for maximum flow and long-lasting durability
  • Turn down exit design routes exhaust under the truck, increasing ground clearance for extreme off-road applications
  • Complete bolt-on kit includes all necessary hardware and factory-styled hangers for direct fit installation in stock locations
  • Mandrel bent construction eliminates restrictive crush bends found in stock exhaust systems
  • 409 stainless steel construction resists corrosion and maintains appearance over time
  • Backed by Flowmaster's Lifetime Limited Warranty for peace of mind

This cat-back system is designed for easy installation using existing mounting points and includes everything needed for a complete exhaust upgrade. The turn down exit configuration is ideal for lifted trucks and off-road vehicles where maximum ground clearance is essential.

The best

I'm a first time buyer of your company and was impressed with the service. I Goggled what I needed..... your company website popped up, and I placed an order. Very easy and stress free! Will be buying from you in the future. Thanks!

vvvv

great product and service

I love my BBK parts, especially the fact that they are American made. The only problem I had with this order was from FedEx. I never received any shipping information until they had been sitting at my driveway for 24 hours. I received a notice that they were shipped and delivered all in the same day.

Quick and easy transaction
