I have the Sceptre pipes with 2" baffles and they are AWESOME!! A friend of mine has an '04 Speedmaster and he runs the 1.5" baffles and there is a subtle difference between the two....my 2" baffles are 'slightly' louder than his, but not by much. I've got 8600 miles on my pipes and I have no complaints about them....no discoloration etc etc..

'02 TBA,904,Scepter,K&N,and a little bling too!
