I get a lot of compliments on these. They are similar to NH togas but different enough. They are different to NH's in that they are stainless steel construction, they don't taper as much towards the tailpipe, the tailpipe is a bit shorter, no baffle holes in the tailpipe, they also sound a bit deeper and a bit more "growlier".
after reading the loudness scale thread, i would rate these around an 8.0-8.5 as they are a bit louder then Hydes.
