I find that RM01A is quiet as mouse when idle but when VTEC kicks in, thats a whole different story, it screams! Having said that, when revving it hard, its quite loud (I would rate it moderate) but not those kind of loud that makes your ears feel like exploding. I think it has a nice racing noise and suit my liking.

Personally, I like this type of exshaust and I am really happy with it. Plus now with the RAWRRRR of the GruppeM....feel like Vtec it all the time...LOL

I am yet to dyno it but really haven't got time these days...hopefully i can spare some time in near future.

But in terms of the RM01A, whats it like on idle, rev and vtec? I noticed on videos it has that drone (I hate it) but during cruise/vtec its sweet. I know you have headers as well so it could affect the overall sound.

Powegetter tip is too long for my liking really.
