I immediately installed the long TORS on my speedmaster as soon as I got it. The stock pipes were real quiet. I since have drilled out the last baffle making lots of small 3/8" holes around the exit pipe. The sound is getting better and better the more I drill it. I have no idea of what they are making those baffles of but I can only drill three holes before I have to sharpen the bit again.

It makes a nice rumble at idle and is peaceful and nice on the ears until you get to about 3,500 RPM. Then if you crank it on in 2nd or 3rd it really roars and the bike goes ballistic. I haven't pushed it beyond 6,500 RPM in any gear yet but I will when I find an empty enough road. The roar of the pipes and the sensation of speed when really cranking it on is a real rush and scares the crap out of my wife. I love it.

The only real maintenance the bike needs is to keep the chain clean and oiled at least weekly. Great machine!
