I believe its right on the end of the muffler, where it rounded.

and you should drill four holes like this:

With the Q being where the stock tip is.

can someone else confirm? keep in mind you'll have to increase jetting to compensate so you dont mess up ur engine.

kenny and islandbayy, so i take a long drillbit and put it in the end of the muffler and drill a hole thru the inside of the muffler.. if so, about how long of a bit?

1 ft bit (12 inch). get a bit thats just under the size of the exhaust spout.
