I would love to go to stage 1, but I cant bring myself to put a drill to a new bike. Maybe in the spring.

what do you think is the best way to break the weld? i dont have a metal hole saw. i have a wood hole saw kit.

Sorry I never answered, left the country for a bit, but like Doc said a dremel will do the trick. But, I also see you're done anyhow so this is a moot point now.

A little tip.... If you can use a dremel cut the weld at the pipe.
once that is done use the dremel to cut the cone in a pie shape
around the whole cone. Makes the cone come out with less pulling and banging leaving a cleaner edge. and less chance of looseing up the head bolts.AS the article shows take a punch and mark at 12,3,6,9. use a smaller bit for smaller holes.then the 1/2inbit in the same holes.
at this point start bike and check your sound if it's fine your done.not done drill the same holes between the others and start to hear the sound.
clean up the metal edges and take some black spray paint for gas grills
and spray paint the inside the pipe. your done. It looks great and sounds great.JMHO

I did Stage 1 and 2 and love the sound. Easy to do on the bike if you take your time. For sure use a Dremel to cut the cone out. Thinking about going stage 3 but afraid it will be too loud and no way to go back!

I did this exhaust mod, poor mans BAK with a K and N filter and pulled the AIS (moved the fuel pump while I was at it). I work with a guy who bought his Roadie right after mine and I can pull away from him after these mods. Every little bit helps.

Does anyone have pics or video on stages 2 & 3? I have completed stage 1 but am think about going to stage 3. Any pointers on stage 2 & 3 would be great.
