Description
Overview
The Flowmaster 40 Series Delta Force Exhaust Muffler is built for drivers who demand serious flow and an unmistakably aggressive tone. Engineered with Flowmaster’s proven Delta Flow technology, this race-oriented muffler delivers excellent power characteristics while still providing meaningful sound reduction over open headers. When you shop for exhaust that balances performance with a purposeful growl, this 40 Series Delta Force muffler earns its place in a hard-working exhaust system.
Flowmaster designed the Delta Force 40 Series specifically for racing applications where a muffler is required but a substantial decibel reduction is still needed. That makes it an ideal centerpiece for a performance exhaust setup on a dedicated race vehicle, where you want strong power delivery and a race-ready sound without the full volume of uncapped headers.
Key Benefits
The heart of this Flowmaster muffler is Delta Flow technology, which manages exhaust gases to help maintain velocity and support strong power output. The result is a car exhaust component that works with your engine rather than choking it, while the aggressive sound level lets everyone know the vehicle means business. A durable high-temperature paint finish helps the muffler stand up to the heat generated in demanding exhaust automobile environments.
