Flowmaster Super 40 Series Muffler - Chambered Design With Deep Aggressive Sound

Car enthusiasts, the Flowmaster Super 40 is legendary for that deep, aggressive exhaust note that makes your vehicle sound mean without being obnoxiously loud!

The Delta Flow technology reduces interior resonance and drone while maintaining that classic Flowmaster sound profile.

The larger case design provides excellent performance for high-horsepower vehicles while delivering that powerful exhaust tone everyone loves.

Constructed from durable 16-gauge 409S stainless steel with full MIG welding, this muffler is built to last through years of use and exposure to road salt and weather.

The chambered design creates that distinctive Flowmaster sound that's instantly recognizable - deep at idle, aggressive under acceleration, but relatively civilized during normal cruising.

Perfect for trucks, muscle cars, or any vehicle where you want to upgrade from the stock whisper-quiet exhaust.

Installation is straightforward for most vehicles if you're handy with welding or exhaust work, or any muffler shop can handle it quickly.

You'll notice improved exhaust flow that can free up a few horsepower while transforming your vehicle's personality.

That satisfying rumble when you start up and the aggressive roar when you stomp the gas never gets old.

Whether you're building a performance vehicle or just want your daily driver to sound more exciting, the Super 40 delivers that classic American muscle car sound that turns heads everywhere you go!
