RPM is proud to now offer Flowmaster Exhaust systems in two versions for your Mustang.

Force II Exhaust System:
The Force II exhaust system is designed with the latest exhaust technology available. Through this technology, you will experience improvements in acceleration, passing power, and fuel mileage. The key to these performance improvements is the use of mandrel-bent tubing. The tubing allows for superior exhaust gas flow, while aluminized steel construction has been utilized for its corrosion-resistant qualities. This kit features the 50 Series Delta Flow 3-chamber muffler that'll give you plenty of Flowmaster sound under hard acceleration, but low sound levels while cruising.

MagnaFlow exhaust is built of aircraft-quality T-304 stainless steel -- stainless inside and out, not mild steel, not aluminum, not coated aluminum, not just wrapped with stainless on the outside for show. Coating techniques, such as aluminizing, can somewhat prolong the life of mild steel, but coatings suffer at the weld points. And, comparing aluminized steel to T-304 stainless steel is like comparing gold-plated metal to solid gold! T-304 stainless steel has the highest chromium content, making it the most resistant to corrosion and therefore the most desirable material for a long-lasting exhaust system. Note: Only the flanges are not stainless. In our twenty-year experience, we have found the 3/8"--1/2" flanges are so thick they will never affect the performance or longevity of the system.

MagnaFlow Stainless Steel bolt on Cat-back™ exhaust system for the 99/04 V6 Mustang is designed with the latest technology to provide the highest level of performance. This Stainless Steel system was engineered exclusively for the 99/04 V6 Mustang with one thing in mind: performance. All stainless steel piping mandrel bent for superior exhaust gas flow, and is a key to the system’s performance. Both mufflers and piping are fabricated from stainless steel for corrosion resistance. This is a simple bolt on and can be done at home in less than one hour, requires no welding or special tools or brackets.
