I used a sawzaw and cut just behind the weld, because you would have a very hard time cutting through the weld. i used a mig welder to put it back on and i left my muffler and my rear rack on and had no problems, just take the fender extender off so you can get in there better.

I took mine off the bike, and sawed it in a band saw right thru the weld, when I re-welded it you could not tell that it had been apart!

so how do you guy like the sound after the mod, how much louder is it? and how much gain did you get?

I can't tell much performance difference, as I haven't(yet) done the snorkle or jetted it. Any day now.... It is louder, but can be quiet if you stay off throttle.

As far as the sound i can't tell hardly at all. maybe a little deeper sound. I could tell a big performance difference. my throttle response greatly improved. i beleive that you would have gotten the same from an more expensive aftermarket product. i really was impressed, and glad i did the mod.

How many holes did you drill Matt, or did you follow nyroc's exactly? and i see from your sig. that you have no other mods other than the black spring. sounds encouraging.

I drilled 6 1/2inch holes with a 12" bit. i drilled them really deep until i ran out of room. i did not bore out the end cap because i beleive that the end cap is the spark arrestor, so i did not bore it out. but after that i just welded it back on. i was really surprised of the power i gained. i highly recommend it if you dont want to buy a aftermarket pipe. i figured that i had nothing to lose, and being a college student i could use $200 on something i really need. i was really happy with the mod, and you could not even tell i had done anything.

I drilled 6 5/8 holes and it sound like a Harley
