After being involved in this thread, I got a little bit curious and opened the valve. Definitely no difference with the way it runs, of course, but the sound difference is pretty much nonexistent. I guess I can tell if I blip the throttle in my garage, that’s about it.

My ricer side can’t help but think I might be gaining a couple of ponies with the Hondata tune supplementing the slight extra flow at low rpm, so I’m leaving it open for now.

Yeah, with the valve open I think there’s a little more low rumble at low rpms. I’ve found it’s not a significant enough difference (to me), despite my initial excitement. But hey, it was easy and FREE to try it.

Yeah the exhaust is still going through both resonators and just a tad bit smaller muffler. So the change will be minimal. Once I get my downpipe hopefully some better sound will come out of that engine. It sounds like a vacuum cleaner😂.
