So, I've read the all the posts - is there a consensus as to the exhaust valve removal being a fantastic mod, or just meh? Aside from throwing codes, is this a beautiful thing?

I wave to everyone on two wheels (unless it's a car).

This thread is almost as bad as an oil thread. I have read so many opinions on what the exhaust servo does but never a dyno chart. I think if you just remove the valve without tuning the engine you are not really getting the desired effect ( smoother/increased hp across the rev range) With the termis, you get the new map and that is making the necessary fueling adjustments for the reduced back pressure by keeping tube exhaust flap open. Of course this is just my opinion with no dyno results to back it up
