Makes driving enjoyable and works as resonator

Flowmaster mufflers often have the bad reputation of causing cabin drone/resonance according to people. However, this one does the totally opposite. It still maintains a nice deep tone and nice sound when stepping on the pedal. People believe there are hundreds of horsepowers underneath the hood, even though it's approximately 165 BHP.
Note: This muffler or resonator as it also function as, is combined with a DNA Motoring catback.
The cabin drone definitely reduced a lot and the overall volume also quiteted down a bit to a nicer level. My car still drones with the Super HP2 around 1800-2000 RPM, but a lot less than 1500-2800 RPM that it used to. Cruising on the highway is now like a dream. Instead of listening to music from headphones, I can finally use the speaker system from the car during cruise.
