On full open, or even 75% open, it is BONKERS loud. Plus, it opens under my seat, so I feel the pulsation of the exhaust. By lightly tapping the throttle, I can pop it as many times as I want when getting off the gas. In fact, I can make it sound like a gattling gun with 10 pops. hahahha

It does NOT sound refined, it sounds like a car with no mufflers. I'm probably gonna run it on about 25% open or so, because I attracted a lot of cops within 5 miles of road. Its REALLY fun to see a cop ahead thats waiting at an intersection that knows you're loud, but you close the valve, and you're dead silent. Then half a mile later all hell breaks loose again. Its hillarious

A lot more bass, and a lot more volume. crazy loud. let me repeat myself again. its loud!

Will take clips soon.
Good times for sure. I had cut-out/bypass valves on my turbo 240-Z and it was fun to partially close-it to feel the torque differences from full open. It was a single pipe 3" with zero 90's, only 45*.Boosted cars don't like much back pressure but NO BP seemed to weaken things in different rpms.
