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.
