From what I remember of the gearing on a 240, I’m guessing… 80+%? Not sure about the rest of you, but IMO highway drone is the ONE unforgivable sin in an exhaust. In Canada, that’s pretty much where you are all the time, you’ll go nuts with annoying drone in your ears. Thank you for this post! I was starting to get the impression I was the only one that thinks obnoxious drone doesn’t equal power. lol Whenever I’ve sat in a car with an aftermarket exhaust, on the highway or just cruising, omfg. BZZZZZZZZZZZZZZZ. Maybe I can fuck with the resonance frequency somehow, so it goes higher or lower than at the highway cruising range of 3000-3400rpm. --- _[View the full topic](https://forums.speedlife.net/t/stealthy-exhaust/129881)._
