Flowmaster has been a racer favorite for years, because of the sound and because of the performance. Now, they’re pushing hard to build a reputation for the ultimate in durability with exhaust components made from 409 stainless steel. Now, there’s nothing wrong with powdercoated or aluminized steel – it’s inexpensive and durable, and the price makes it an attractive choice. But if you’re looking for the very best, and you want an exhaust that will withstand years of exposure to anything you can run through the motor or under the car, then 409 is the clear choice.
It’s more than just mufflers, though. Flowmaster also has axle- and cat-back kits in 409S, like the ones for the 2010 Camaro in both SS and V6 flavors – it’s the same dyno-proven performance you expect from Flowmaster, with a 10-year warranty.
