anyone got any reccomendations? My buddy who works up at a lube center told me that flowmaster lost their U.S. Patent so pretty much EVERY other muffler company has stolen their design and tweaked it a bit to make it a little more unique. Is Magnaflow more expensive than flowmaster? and which is better?

 

If you just want a cheap low restriction muffler, we used to use theCorvair Turbo muffler. If you want a 'state of the art' muffler, that you can tune to get the max horsepower out of your ride, I'd go with the $upertrapp disk tuneablemuffler.
