Okay... It seems whatever exhaust you choose, the drone's always around the 1,500 ~ 3,000 rev range.

We already have kind of a dynamic valve in the stock system. I was wondering if any fabricator or electrical engineer can tap into the ECU and make a valve that shuts 50% from 0 ~ 3,000 and completely opens up beyond that.

That way, people can run the smallest mufflers and have the best of both worlds. There are already a few systems on the market with active butterfly valves but they cost a fortune.

Someone with the expertise should step up and make a bucket-load of money.
