Bike I just got has stock street glide mufflers on it that somebody knocked out the center plugs in muffler. Dosent sound the best. Is there anything I can do to make them sound a little better.I dont have funds just yet to replace them. Help me please

 

Look at craigslist for a set of aftermarket mufflers on the cheap until you can pull the trigger on the ones you want. There is no easy fix to your 'modded' stock mufflers. Hell, you can probably get a free set of stock mufflers from the dealership to change out. It will be quieter but sound better...If you were close to me I'd give you a set of stock ones, I must have a dozen sets of take-offs here at the shop.
