Review on 🚀 Enhance Your Ride with the Black Widow BW0013-2 Exhaust Muffler: Unleash Power and Style by Matt Eason

love the sound especially when driving around the area it has a nice sound when stopping you can hear the engine downshifting sounds great. As you can see I added the aj tube because without it the hum was bad on the highway between 2100-2600rpm, now with the j tube it's just tone and once the tone picks up speed, the audio goes back to where you can speak . Without the J-Pipe it was about 87dB, and the J-Pipe reduced it by 10dB. Brewed in a shop that costs money.
