Description
Take Performance Up a Notch. The Flowmaster Super 50 Series Center/Offset Oval Muffler (2.5”) will take exhaust flow to optimum levels, resulting in a boost in horsepower and torque for your Mustang. Designed to be a larger, more impressive version of the famous 50 Series mufflers by Flowmaster, the Super 50 Series Muffler is the perfect addition for your large displacement engine. You will experience both power and mileage gains, giving you excellent bang for your buck.
Refine the Muscle Car Sound. Unlike lower-quality mufflers, the Flowmaster Super 50 Series muffler won’t produce a deafening, obnoxious whine. Instead, the special tuning chamber will reduce interior resonance and the larger case will give greater sound control, combining for a classically deep but mild tone. The rich roar from your Mustang will earn the respect of other drivers and muscle car enthusiasts, on and off the road.
Premium Construction. Fabricated from 16-gauge 4095 stainless steel, the center/offset oval muffler is fully MIG-welded for excellent durability. By choosing the Flowmaster Super 50 Series muffler, you are choosing only the best, American-made option for your Ford Mustang. With a natural, stainless-steel finish, it will complement the classic style of your muscle car.
Modifications Required. This Muffler was designed to be used on mutliple applications, as it is not a direct fit replacement part. In order to install this Muffler properly on your vehicle, some modifications to the exhaust system will be required.
Limited Lifetime Warranty. Flowmaster backs their mufflers with a limited lifetime warranty.
Application. The Flowmaster Super 50 Series Center/Offset Oval Muffler (2.5”) is designed to fit 1979-2004 Ford Mustangs, with the exception of the 1999-2004 Cobra models.
