Straight to start-up:    • 2021 Mazda 3 gen 4 Hatchback 2.5L Tur...   • 2023 updated video with new parts added! • Update! '21 Mazda 3 Hatch 2.5L Turbo + Magnaflow A-B Exhaust + CS 63.5mm MP + BMS Stage 2 intake:    • 2021 Mazda 3 gen 4 Hatch 2.5L Turbo /...   • Newly installed Magnaflow Exhaust for the 2021 Mazda 3 Turbo hatchback Rev'd to 4500 RPM at max. A low tone overall - Use good speakers or a subwoofer to hear it precisely. These cars don't rev high during driving on stock tune, so this is rev'd high enough to get a good idea of the sound profile. • There is no drone at highway speeds, and barely noticeable once warmed up at idle. Taking off from stop, you hear a pleasant low pitch that is close to a rumble. The exhaust should open up over the next few thousand miles, and I will post a follow-up video then. • UPDATE: 30 mile drive test after installation. I ended up getting better overall gas mileage than normal. All stats pulled directly from the vehicle fuel monitor. • 29.4 miles driven. 45 minutes total drive time. 90% highway / 10% street, with some stop-and-go on the highway. • 28.8 mpg for the trip. Normal avg 25.5 mpg.
