Looks like the piping is only 63mm inner diameter at the flange to the catalyc converter?
Here is a nice pic of my 70RR for comparisation, you cans ee the muffler is TWICE as long as the 70RS muffler..

The exhaust is pretty darn quiet from the outside, but inside there's quite a bit of drone in the 3-4k range, both with the hfc and test pipe. I think the exhaust still needs a few hundred miles put through it before I can tell for sure.

My 70RR toned quite a bit down with the drone level after about 700 miles on it...
