To drill out baffles, or not to drill out baffles
Ok... so I currently have a stock 48 and would really like to make it louder, cheaply until I can save up some coin for new pipes, intake and tuner. I've read a bunch of forums about drilling out the baffles. Some say it's OK to do, others say it is bad to do.
I would really like a definitive answer on this from someone who knows about the mechanics of what this will do to back pressure, performance, etc. I read the info here: http://www.harley-performance.com/harley-exhaust.html , which was informative but I still would like to know what would be effected by drilling out the baffles on the stock exhaust.
I know this topic has probably been discussed MANY times but it seems that there really is no black & white answer. All I do know is that the stock exhaust with the baffles is ridiculously quiet. Almost embarrassing to say it's a Harley! LOL
I would appreciate any help or advice anyone can offer! Thanks!

I bought a second set of stockers on ebay and used them in case I didn't like the sound, and you may not.
I took them and removed the baffle plug in the center of the baffle, them removed baffles completely, double the size of the holes in it and added three more rows of holes to the aft end. Then welded them back in and I like the sound ok for now, til I find the two into one that I want.

I love the sound of the drilled baffles on my 48, sounds like a Harley without being overly offensive to my neighbors!
I simply drilled a 3/4" hole in the baffle plate of each muffler, and it sounds great!
I fitted X14iED's as a precautionary measure and I have to say my bike runs and sounds like a dream.
A friend of mine has V&H Short Shots with quiet baffles on his 48 and for me they're too loud, I'd have a headache after 100 miles!
Go for it, stock mufflers are easy to pick up on Ebay if you need another pair for any reason
