Aggressive Sound. Rev your engine to aggressive levels with the Flowmaster Outlaw Race Shorty muffler. The Shorty is designed for car classes that need mufflers but don't have set sound specifications. It allows for minimal decibel reduction without decreasing horsepower, torque, and overall performance.

Small and Lightweight. This small, round muffler has a 4-inch diameter body and is only 6.5 inches long. It features center inlet and outlet positions and has an inlet pipe connection. The lightweight design makes this versatile muffler suitable for race class rules. The Shorty's round case makes it easy to install when space is limited, and it has no internal packing that needs to be blown out. It also generally provides more power than open headers.

Durable Stainless Steel. Made from fully welded, corrosion-resistant, 16-gauge 409S stainless steel, the Flowmaster Outlaw Race Shorty is designed with maximum horsepower and torque in mind.

Application. The Flowmaster Outlaw Race Shorty is a perfect race-ready muffler for your 1979-2004 Mustang. You'll need to make some adaptations to mount it to your exhaust system.

I have the super 44s on right now but if I installed these outlaws in place of the super 44s would I be losing any performance benefits because these are more straight through ?

  • Depending on your specific setup, the Flowmaster Outlaw Race Muffler may cause a slight loss in low end power production and throttle response. This will be based on the exhaust flow and backpressure on your current setup.

Does any one know or have any information on how this sounds/compares to the slp loudmouth 2? I cant seem to find any sound clips of this particular outlaw muffler.

  • The Flowmaster Outlaw Shorty Race Bullet Style Muffler will be significantly more aggressive than the Loud Mouth 2, with the Flowmaster being more Akin to the original Loudmouth mufflers.

What exhust pipes is best for this Item?? I plan to renew all my exhausts under my 1995 mustang v6... Maybe will add long headers.

Deafdude77

  • if you are placing the entire system we sell exhaust combos or the exhaust systems in 3 major parts. Buying them in sets or whole will save you in the long run. Or you would have to modify the exhaust system with straight pipes. Here are a few options. http://www.americanmuscle.com/flowmaster-force2-catback-9497v6.html Or combo units minus headers http://www.americanmuscle.com/9498-mustang-exhaust-combos.html#shop-by2

Can this product replace my 40 series mufflers on my dual exhaust?

  • This muffler can replace your 40 Series muffler. You will however need to make some adaptations to mount it to the exhaust system you have on your vehicle.

    The Best Choice!

    I have these outlaw mufflers on my 01 mustang gt and it was best choice I ever made for my mustang. I've tried other muffler that were good but these are the best. Very aggressive and respectful without a drone. Heads will turn and look at you and say, "she sounds beast bro." "What you got under there?" I would say, "It's Outlaws Mufflers, all day baby!"

    outlaws

    Can't truly review this product.,as I lowered my mustang before the mufflers came in ,now there is no room underneath to keep them from dragging . But I'm sure that they would of sounded badass. So I rate them a 5.
