FYI Tips and tricks,,,

Baffelectomy stage 1

I did It,,love It,,

Twisting and torqing off the mufflers will Loosen the header clamps at the top.....
You have been warned.

My cost : bout 3 bucks for a 3' 3/4" threaded rod..
One whack on each muffler was all It took.

I already had the Big Freakin Hammer :=)

Factor in the cost of vandalism to your home, cars and bike,
by your neighbors who get irritated by your needlessly loud pipes aggravating them.

Enjoy the sound of your pipes and expect to say: "huh?" a lot when you get older.

Maybe folks are saying loud pipes when we really should be saying a little louder, my bikes a little louder than normal but not to the point where some clown would throw a brick at me as I ride past and the local cop would be writing me up for noise pollution, even then I think the normal rider would pretty much idle his bike into his neighbourhood.imo

I used a 1/2" rebar and put one hole in each. Made for a nice subtle rumble, not overly loud.

I have a Supertrapp 2:1 now. Still not too loud, but deep.

Huh?

when I got sick of my bike sounding like it belonged on the Jetson's I used a specific tool...my big screwdriver just made sure the holes were same size with both pipes. Then I checked the colour of plugs for burn after I rode it around for a while they remained a nice tan colour ...all good.
