      Long-Lasting Steel Construction. The Flowmaster Original 40 muffler with offset inlet is constructed from high-quality steel and features a black powder-coated finish. This muffler upgrade is incredibly well-designed, offers exceptional longevity, and is resistant to rust, corrosion, and UV damage.

      Aggressive Sound. If you’re searching for a muffler that will deliver the most aggressive sound, the Flowmaster Original 40 is the top contender. It is designed for street use only and strip vehicles. The sound waves produced can be heard inside the vehicle, creating a unique driving experience.

      Easy Installation With The Right Tools. The muffler is relatively simple to install, provided you are familiar with similar projects and have access to adequate tools. However, for some vehicle owners, a professional installation is recommended. Installation can take 2 hours to complete.

      Limited Lifetime Warranty. Flowmaster backs the product with a limited lifetime warranty against defects in craftsmanship and materials. Note that this non-transferable warranty doesn’t cover product failure due to incorrect installation, neglect, or abuse.
