Something to consider when changing or altering your exhaust..... You are changing the flow of air through your motor. The intake of air may be affected, and you may need to rejet and rebalance your carbs, which, is THE MOST FUN EVER!
I've heard of people drilling holes into the end of the baffle. I've heard of people removing the end of the exhaust, and taking the baffles out completely, thus making it a straight pipe. I personally took apart a canister muffler and fabricated my own custom baffle that lowered the restriction in the exhaust. Yes, it changed my airflow significantly, and I had to rejet. And that was on a single cylinder bike, so recognize the risks involved, and the time involved in making the bike run properly after your 'mod'.
It's fun, and louder, but it's alot of work also.
