Debaffling stock can

Well i started Debaffling this morning as i foung what to do at SVrider.com. So far only have the holes drilled and wow, what a difference already.

I would say its almost twice as loud now, even louder when it out i would imagine.

Now the question is. In a month or so am gonna buy either a viper or scorpion can. How much louder are we talking? I seen a good 50 videos on the net on all kinds of end cans for sound but in my opinion nothing compares to actually hearing it. I watched a video of a before and after removal of baffle on the stock can, and i couldnt tell any difference on the video. Now i just did it its a whole new world of difference, and thats just a few holes drilled.

I dont want to go with a micro can as i think it looks hideouse on the bike, A r6 it looks nice, but not the SV. The difference between the 55'' and 44'' (i think the other two sizes are or close) would that make a world of a difference on the noise? I dont like the long one or short one, going in the middle if its reasonably loud
