I pretty much drive around in track all the time but if this is significantly louder I would wan to know if I could quiet it down.
I am assuming there will be some power gains as well...
my plan is to do cat back and then wait for a high flow cat that goes in stock location that doesn't throw a code...
I hear our exhaust manifolds are excellent and the real hold up is the primary cats..

It’s on the car but I need to make some adjustments. I think it settled during my 10 minute drive. I’m still going to do a full write up once i get a chance to drive it more, but I’ll share my initial thoughts.
I used an app to measure decibels. I’m not sure if it’s correct, but it’s a reference for measuring if the BBE is louder. Stock was 78 decibels from 3-4ft away. BB is 99 decibels. The valves don’t seem to make much difference but I haven’t measured decibels closed yet. I am having a hard time noticing much difference from inside the car (valves open vs closed). I think I’m getting some drone, but I haven’t cruised over 55 mph yet. It sounds good with the windows down, but I was limited due to rain. The stock rasp is gone, but it’s still too early to have a substantiated opinion. I need to adjust fitment a little bit and wait for good weather.
