Product Details

The Flowmaster Force II Cat-Back Exhaust System delivers enhanced performance and an aggressive exhaust note for enthusiasts seeking improved flow and sound. This complete exhaust system connects after the factory catalytic converter and features mandrel-bent 16-gauge stainless steel tubing for maximum exhaust flow and long-lasting durability.

Key Features:

  • Super 50 Series performance muffler produces a mild to moderate exterior exhaust tone
  • Mandrel-bent 16-gauge stainless steel tubing maintains consistent diameter for optimal flow
  • Polished 304 stainless steel tips provide a premium finished appearance
  • Includes OEM-style flex-pipe joint to accommodate engine movement and reduce stress
  • Uses factory hanger locations for a direct-fit installation
  • Complete hardware and hangers included for straightforward bolt-on installation
  • Backed by Flowmaster's lifetime limited warranty

This cat-back system is engineered for easy installation using factory mounting points, eliminating the need for welding or modifications. The Super 50 Series muffler balances performance gains with a refined sound that won't be overly loud for daily driving, while the stainless steel construction ensures corrosion resistance and long-term reliability.

Cheapest price I found online

Service was fast and great

Please deliver ASAP

Website is pretty easy to use. Good product selection. By far the best price for a lot of items. My Bilstens were at least 10% cheaper at Autoplicity than any other websites (rockauto, amazon, partsgeek, 4wheel, etc, etc). Shipping is reasonable. Great ex

quick and easy

everything was good thanks

No common

The headlights look great the price was fair but the lights don't operate correctly.

Easy

sweet

Autoplicity cares about there customers. I ordered a flash programmer and got to the last page and never got a confirmation of the order. I used the website chat and talked to somebody about it right away. So I ordered again and got a conformation. But both went though. Autoplicity called me next day a.m. to see if I made a mistake. Thanks for letting me know and correcting to one order. Saved me from shipping back a product I dind't need.

Great web site! I always research products before purchace,I called customer service and spoke to a rep that knew his products and was very helpful.

Lowest price on the net for what I purchased and received it within 3 days of placing order. Great website, great prices, & reasonable shipping charges.

Fast Shiping Good Services Verry Good Pricing
