Delta Flow® Chambered Technology

1. Resonant Tuning Chamber™ Captures and cancels specific resonance inside the vehicle.
2. Power Chamber® Creates a negative pressure that helps scavenge exhaust gases
3. Delta Flow® Technology Provides advanced noise cancellation by separating and recombining pulses at precise phase shifts and increased exhaust scavenging.
4. Low-pressure Balance Chamber Blocks power-robbing atmospheric pressure from entering the system.

Delta Flow technology® provides superior scavenging of exhaust gases. This results in increased horsepower, torque, and fuel economy while reducing exterior sound levels and interior resonance. The deflectors function properly only when they have been precisely placed and welded to exact specifications. Only Flowmaster’s state-of-the-art electronic sensing equipment places components to a tolerance of +/- .004”, the tightest specifications in the industry.
