Description
Give New Life to Your Mustang. With the Flowmaster Super 40 Series Offset/Center Oval Muffler (3”), you'll improve your Ford Mustangs' exhaust flow, getting exciting performance gains. Watch as your horsepower, torque, and engine efficiency are kicked up a notch, all thanks to the increased airflow. The Super 40 Series mufflers have outpaced older, two-chamber mufflers on a number of dyno tests, so you can be confident you are making the right choice for your Mustang.
Intensify the Hot Road Sound. The innovative design of the Flowmaster Offset/Center Oval Muffler will refine and strengthen the natural sound of your Ford Mustang while avoiding the annoying drone that comes with other, lower-quality mufflers. On and off the road, you will command respect when your muscle car roars to life, silencing the competition.
Quality Craftsmanship You Can Trust. The American-made Super 40 Series muffler is not only designed for performance but it's also a piece that lasts. Constructed from 409 stainless steel, it will hold up to many miles on the road. The natural stainless steel finish achieves that classic, stylish look you are looking to achieve on your Ford Mustang.
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 40 Series Offset/Center Oval Muffler (3”) is designed to fit 1979-2004 Ford Mustangs, with the exception of the 1999-2004 Cobra models.
