Description
Classic Muscle Car Roar. Bid farewell to the restrictive muffler that is hindering your Mustang's performance by enhancing exhaust flow with the Flowmaster Super 40 Series Oval Muffler. This muffler does more than add aesthetics to your ride. It features two-chamber technology that creates a signature Flowmaster exhaust sound. Notice how your vehicle achieves better horsepower and torque with this muffler's inlet/outlet design, which has been built using the highest quality aluminized steel.
Remarkably Efficient Design. Replacing your stock restrictive muffler with the Flowmaster Super 40 Series Offset/Same Side Out Oval Muffler - 3.0 will be a decision you never regret. Additional engine power will be released via the robust aluminized steel construction, allowing for the simple transfer of exhaust gases. As a result, your Mustang sounds better, becomes more efficient and emits fewer harmful gases.
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.
Warranty. With every purchase of a Flowmaster Super 40 Series Oval Muffler, a Lifetime Limited Warranty comes as standard. Flowmaster's warranty can be redeemed by the original purchaser. Coverage remains valid for workmanship or material-related defects. It is void in cases of misuse, poor installation and normal wear.
Application. The Flowmaster Super 40 Series Offset/Same Side Out Oval Muffler - 3.0 is specially crafted for application with all Mustang models between the years 1979 and 2004. The set is not suitable for 1999-2004 Cobra Mustangs. The muffler contained in the box features an offset configuration to perfectly match its inlet/outlet diameter.
