I have done some research but can't seem to find any information and there may be a reason that no one does it.  I'm trying to get a better flowing muffler on the cheap so that Srinath can get me the jets that I need.  He suggested coring the muffler and gave me a part to help out with the process. 

It would be nice to find out if anyone has any information.  It would also be nice if it gave it a little deeper sound and wasn't extremely loud.  If anyone has any ideas on how to put it back together so that I could repack the muffler every once in a while that would be great as well.  I'm not opposed to cutting down the muffler but I figured if I left it stock it would be better to actually muffle the sound. 

Thanks,

you'll need an angle grinder with cutting wheels, a small job welder, and creativity.

I looked around on this same subject when i was thinking of altering my muffler, but found no truly 'good' way of doing so. So with about 8" of exhaust pipe, a cheap muffler off craigslist, and about 15  minutes of help from a local muffler guy, I got a custom setup which works well and sounds great.

There is the "drill out" method, but i've seen very little contentedness with the results.

Thanks for the response.  I honestly forgot I started this thread.  Does anyone else have any opinions and/or thoughts?

I work with my hands and am decent at making things.  I do have a welder, angle grinder, and a good amount of tools.  I still haven't had a chance to start chopping yet but if I do I'll try to take pictures and post.  I have to fix my badly leaking fork seals first.

cut your front catalytic converter out it is situated just after where the pipes go 2 into 1.Cut through where there are 3 plug welds on the pipe  .you will be suprised at the increased responce .There is a second cat at the very start of the muffler just leave it alone .Exhaust sound is awsome but you may need to increase jet sizes .
