I didn't think it was too loud, not with the new "cone" end cap.
It is a fair bit quieter than my Two Brothers.
You should hear it at 8000 RPM. From 4500 on she takes of like a scalded cat. HEE HEE!

man the black rack thing really caught on.

any pipe that doesnt have any baffles and is just straight through will be about the same db.... i know the big gun with out vortex and with out the quiet core is really loud. muzzys are loud too.i have herd just about every pipe personally. except the PC

 

Thanks for the link westoz, the 2bros was #2 on my list of desireable exhausts. That 2bros in the youtube didn't sound too excessively noisy. Not enough to rule it out at least. PC is quieter than 2bro, thanks.

 

Can length & core diameter can greatly effect sound output dispite sharing a sdtraight through design.
