Product Description

Flowmaster Force 2 System
For the person who is looking for a complete catback dual exhaust system with a milder tone for their 1987-93 Mustang GT, this Flowmaster kit is for you. With easy fit in mind, these Force II systems from Flowmaster are mandrel bent for maximum performance and include specially selected mufflers. Force II systems deliver a moderate interior and exterior tone and are suited to the enthusiast who wants their performance to be heard, but not overbearing. Like all Flowmaster systems, the Force II benefits include improved throttle response, power and mileage. Designed for an easy fit, these Mustang exhaust systems include all necessary parts and hardware for easy installation.

Flowmaster Quality
Since Flowmaster mufflers use sound energy cancellation technology, you don't have to worry about "packing material" deteriorating and getting louder after as little as a few months. The interior case volume of the inside of a Flowmaster muffler is far superior to that of a "straight-pipe" or "straight-through" muffler design. Imagine filling a "straight-pipe" or "straight-through" muffler with water vs. filling a Flowmaster muffler with water. Which one do think would hold substantially more volume? The deflector in a Flowmaster muffler acts as a one way check valve eliminating reversion back to the engine and creates a low pressure area to help scavenge the exhaust. Flowmasters unique style of H-Chamber designs help control interior resonance inside the cab area of your vehicle. "Straight-through" muffler designs cannot. Flowmaster uses fully welded construction for added strength and durability to last even when installed on high horsepower engines.

    5 Stars   Sounds Mellow and Great, even with Stock Cats
    By on 4/7/2014
    1989 Mustang GT: The Force II fatback system is worth he extra money over the American Thunders. I have not found any review on this system and took a chance. The tone is mellow yet still aggressive. Especially when you punch it. The highway drone is bearable, and low to no drone if you are cursing at 70mph or below.
    I bolted this catback up to my stock H-Pipes w/cats on my 89 GT. I have BBK Shorty unequal length headers and the combination makes great sounds and a great "punch." The power caught me off guard and I was fish tailing coming out of the shop. Seriously. And best of all, if you are idling down the road, you won't wake the neighbors and you won't announce your presence. Unless you rev it up! So - Lastly, this is - SOUND ON DEMAND! Great choice.
    Thanks LRS for fast shipping.
    P.S. Buy 4 new rubber hangers, and new bolts to H-Pipe for a easier and correct install.

    Yes, I would recommend this item to a friend!

    5 Stars   Perfect OEM fit
    By on 2/25/2017
    I finally got something with a little more rumble than the original OEM mufflers had without making it overbearing. The mild tone of this set is pretty good for my convertible.I didn't want the exhaust sound to take over everything else that takes place in the cabin. Great fit

    Yes, I would recommend this item to a friend!

    2 Stars   Awesome sound, bad fit, poor quality. Disappointed.
    By on 5/15/2017
    The good, By far the best sounding catback for a fox body Mustang. The bad, the flares where it bolted to my brand new BBK h-pipe were not flared enough, they barely covered the h-pipes flares, I had to flare them out more by hand to get them to cover the h-pipes flares evenly. The tail pipes are bent poorly, and hit my stock upper control arms, so now I have to buy tubular control arms so my $400 something dollar catback will fit my car. The piping must have banged around in the box during shipping or something because the flares were also bent on 2 pipes and again I had to straighten them out by hand. Way to much work had to be done to correct problems that should not be their from a high dollar exhaust like Flowmaster. I would not recommend Flowmaster anymore because you can just buy much cheaper no name catbacks and the quality couldn't be any worse than this was. Luckily I was a skilled auto tech and in the end I made it work and it's sounds awesome, but not worth the money, kind of feel a little ripped off by Flowmaster.

    5 Stars   Great system
    By on 6/22/2016
    I bought this set about two weeks ago and put it on yesterday. It is pretty straight forward to install and the noise is mild. It is exactly what I was looking for. It is mild but it get a bit louder when floored, which allows to have great city driving without feeling much vibration or noise inside. Great addition to my 1990 GT convertible. When I put that top down, the tone is just superb. I would recommend these to anyone who does not look for an overbearing tone but instead a mellow V8 tone.

    Yes, I would recommend this item to a friend!
