Description

Get every pony of the famous Flowmaster Exhaust System experience without the neighbor-waking, music-stifling blare of their loudest pipes. Flowmaster Force II Exhaust Systems are aggressive when your foot's down and mellow at cruise with less interior resonance.

With a Flowmaster Force II Exhaust, you instantly feel a 5% - 10% boost in acceleration and passing power, plus up to a 2 mpg improvement in gas mileage—just like the feel of Flowmaster's renowned American Thunder Systems. The difference is in Flowmaster's quieter chambered muffler that mellows the muscular sound without reducing power.

Adding to the Force II package is a set of mandrel bent pipes custom-formed for your ride, plus all installation hardware, and even a stainless tip for most kits. Mounting it to your vehicle is easy—many systems can be bolted on at home in less than 1 hour. And, your Flowmaster Force II Exhaust System is backed by a 3-year warranty.

"Sounds great, nice dull drone in cab at 70mph. A little louder under accelleration but not oboxiously loud. Install took about 45 minutes only because clamp/hanger for exit end of muffler didn't fit to small. Otherwise great product, at a great AutoAnything Price."

"After a 150,000 miles of new york weather and winter salt I needed a whole new cat-back exhaust on my superduty . I spent about a day chasing around "factory replacement parts" from a total of 4 !! big name parts stores before i even made it to my shop to begin work. I get the truck on the lift and remove the old system only to realize that the install was going to require more custom adapting etc. then i cared to do and as i added up what i'd spent on the parts i became even more discouraged after realizing i'd spent almost 300.00 dollars on parts (and that was my shop price)actual cost for a customer off the street would be closer to 500.00 + that were sub par in quality. So i got on the phone and called 2 big name performance parts companies i have used in the past and got a "decent" price BUT they both had "extra" fees , so i called the place that should have been my first call "AutoAntyhing" and got a "GREAT" price ( i saved close to 80.00 dollars compared to my initial investment) and best of all i had the parts within less then 3 days . The kit literally bolted right in. The only thing i would reccomend is using heavier duty exhaust clamps then the ones provided with the kit if used on a high performance of severe work duty application ( but thats just from my experience and in probably 90% of standard installs the flowmaster clamps work great)."

"I really like this system. Makes my Stang look, and sound like a GT. It doesn't sound real loud like a GT, but when you start it up, or go in passing gear it sounds hardy!! The tail pipe tips looks great compared to the single one I had. It took about an hour for the garage to swap it out. I would like the warranty coverage to be longer than 3 years!!!"

"I received the Flowmaster within a few days of ordering. Installation was a breeze. Everything went together and fit perfectly. Best of all, it sounds great - not too loud but it has a deep rumbling sound that lets you know there is an engine under the hood. This is the first exhaust system I have installed. but I would not hesitate to do it again"
