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.

Flowmaster is going through their product line and making their most popular components and kits available in stainless for racers and street enthusiasts who want no compromises in sound, performance, or materials. There’s everything from Super 10 Race Series mufflers to the Super 44 Series, designed to be the most aggressive, highest-performing street mufflers Flowmaster has ever built in a 4-inch case, to the incredibly popular 40 Series mufflers, all with a 10-year warranty.

It’s more than just mufflers, though. Flowmaster also has axle- and cat-back kits in 409S – it’s the same dyno-proven performance you expect from Flowmaster, with a 10-year warranty.
