I have a Dyna muffler coming and was wondering if this will require a carb jet change from stock. If yes what would be the results of installing it before doing any carb changes? Oh yes, I have a stock 2006.

If you haven't modified the carb yet,  buy the Jet kit Lancer sells in the Market place.  He has the best prices.    

If the Dyna muffler is a "stock" take off, then you will need at least a 150 Main, maybe the 152.5.  With the 150, you will need to adjust the needle spacer (white spacer).   With the 152.5, you would need to run it for a bit and check the plug to see if having the bigger main will give you enough mid-range on the needle to keep the white spacer.  It's right at the edge, so climate & altitude will play a factor in your needs.   You might need to have just a little off.  I suggest use washers so you can "go -back",  and make sure the washers fit in the little hole in the inside of the slide.  The first set I used didn't and I was be-fuddled why I was so rich.....  

If it's a Screaming Eagle Dyna, then you'll probably need the 152.5 main, and the 55 pilot jet, and will need to play with the white spacer.
