Anyone know what the inlet/oulet sizes are on the stock muffler. The reason why I ask is because I would lile to replace the stock muffler with a glasspack or a louder muffler.

 

If your taking it to a muffler shop, it does'nt matter. They can whip up an adapter in seconds.To answer your question though,I think its 3" in and 2.5" or 2.25"out.

 

Yeah I think you are right. Thanks! I was gonna do it at home, well, how much do you think it will cost to get done?

I know I can do Duals with a muffler for $200 (done the right way with mandrel bent tubes, fully welded).
