It is certainly a lot louder than i was expecting. On flow masters sound scale it is in the upper 50% of their muffler line up on the sound side. Sound is deep and only slight noticeable in the cab at idle.
Their is way too much drone in the cab. The trade off for cab comfort is not worth it.
It is a well made, well designed product that performs exactly as expected for an amazing price. The welds look good and metal work look good paint was also nice and nicely packaged!
It isn't as deep throated as i hoped for, and actually has some rap/rasp when i get on the gas and crank up the rpm. It has some drone at 1000rpm, which my runaround the neighborhood speed. Highway is good, less drone now.
The sound is horrible. I'm so embarrassed by the sound as you accelerate to get into traffic. Has to cut 1in off my pipe to make the hangers line up.
