Your cart is empty.Wake up the performance and sound hidden in your 3.7L V6-powered 2011-2014 Ford Mustang with a Flowmaster Force II exhaust system. These moderate sounding systems retain the dual exhaust system outlets and are designed to replace the original rear mounted mufflers using factory hangers and connections. With easy fit in mind, these systems are mandrel-bent stainless steel for maximum performance and include specially tuned pair of 60 Series performance mufflers with large 3.50-inch polished stainless steel tips. As a Force II system, it delivers a moderate exterior tone and a mild interior tone and is suited to the enthusiast who wants a subtle but distinctive performance exhaust note. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. The exhaust is a true bolt-on system, includes everything you need to easily install at home with basic hand tools.

I have had these on my car for about a week now and I couldnt be happier. They were easy to put on took about 45 minutes and I am skinny enough I didnt even jack the car up. I am very happ with the easy install and it give it a good tone at highway speed and great tone on take off.

Spent 3.5 hours installing this axle-back exhaust. I blame the basic instructions provided by flowmaster and my own lack of experience. My fat fingers didn't help in reaching the bolts either. After I tightened the last bolt I backed up to take a look at the final product. The exhaust tips were inches away from being centered. Decided I had spent enough time messing with the system and took the car to my local exhaust shop so they could make the tweaks to center the exhaust. I'm very happy with the finished product, great sound and great looks. The exhaust has a nice gurgle/pop after every shift.

I would not buy these again. The sound is just okay, and beyond the “Flowmaster†on the tip, I’d be surprised if these are authentic Flowmasters. There is enough rust blowing out the tip that it looks horrible. Mustang is garage kept, and while is has rained a lot lately, the rust is a true disappointment. Spend more and get better.

Am I the only one who thinks these are horrible?WAY louder than the factory web page and the reviewers imply. Under WOT it sounds like a screaming Japanese motorcycle (which, admittedly is kind of cool as long as you don't want to attract every cop in a half-mile radius), but at moderate acceleration it sounds terrible: boomy, muddy, loud, obnoxious. I was looking for a bit more sound, and a lower exhaust note, but I wanted a clean sound, which these do not provide... especially not suited for a convertible. After one day, I was embarrassed to drive it and put the factory exhaust back on. I'm a 40-something professional driving the refined new Mustang, not a 17 year old in a tin-can Honda.I guess I'm not the only one... I bought these "slightly used" from Amazon, so someone else didn't care for them either and returned them. I hear the Magnaflows might be more what guys like me are looking for, but now I'm a bit gun-shy to try again.However... if years of jacking up your iPod has left you half deaf, and this kind of sound is what you're looking for, I'll say some nice things too. I am not very mechanically inclined, but with a set of ramps and a socket wrench with an extension, I was able to install both these puppies in just 35 minutes. I was able to do so without removing the panhard bar as recommended in the instructions. It took 40 minutes to put the factory cans back in but only because I thought I could do it without removing the panhard bar again, but it's a bit harder to wedge it in going in that direction. After futzing about for 15 minutes I finally decided to remove the two panhard bolts - no biggie - made it much simpler.The tips are definitely nicer than stock, and the mufflers are definitely lighter than the OEMs. Fit was good, and installation pretty easy.And Amazon rocks! Not only do they take it back, but they pay the shipping. Other than my time, no risk to try.

These were put on my dad's Mustang V-6 and man do they sound good. You never would've thought a V-6 could sound as good as his does. The installation was very simple, and we really like the idea that we could change back to stock if we need too for car warranty purposes. Great Buy!

Did all the research, listened to various brands of axle back exhausts for the 2010-2014 v6 Mustangs.Decided to go with Flowmaster Force 2.Had them professionally installed on my 2014 Mustang. However,they did not sound like the sound clips I heard on youtube or American Muscle.I am some what disappointed.Yes it has the deep rumble on idle but once it goes above that, break out the fly swatter it begins to sound "ricey". Was hoping for more of a muscle car sound.The drone is horrible. I have to keep it in sport mode to quiet it down. Flowmaster is a good product, but not for my car.
