Product Details

The Flowmaster Force II Cat-Back Exhaust System delivers improved performance and a moderate exhaust tone for your vehicle. This complete exhaust system connects directly after your factory catalytic converter, replacing the restrictive stock exhaust with a free-flowing performance design.

  • 50 Series Delta Flow performance muffler provides excellent flow and a moderate exterior sound level
  • Mandrel-bent 16-gauge stainless steel tubing maintains consistent diameter for maximum exhaust flow
  • Specially designed resonator helps control interior drone while maintaining performance
  • Includes all necessary hangers and hardware for straightforward bolt-on installation
  • Cat-back design connects after factory catalytic converter for emissions compliance
  • Backed by Flowmaster's lifetime limited warranty

I have dealt with them twice so far and they have been great both times. Price can't be beat and you can get someone on the phone nearly every time you call. Shipping is reasonable and fairly quick. I will definitely shop here again.

Easy Web site to use.

Simple and efficient checkout.

Good!

Great Experience and Awesome website. Affordable price as well

I was told about Autoplicity from a friend on a car forum site that I wouldn't be disappointed with the price, quality and shipping. <br><br>I ordered my part on 7-18-12 and received my item the very next day. That's about as fast as getting some parts from the local auto parts store when they have the parts stocked in an outlying warehouse.<br><br>I will certainly look to Autoplicity first when I need to order engine and other car parts for my 87' Monte Carlo SS<br><br><br><br>

Received Monroe MA770 air shock, fit just wonderful and the installation was easy.

Awesome that you can pay with Amazon!

It was easy
