Well me and a friend of mine went to his grandfathers shop and chopped off the old flowmaster 40. (btw...it sounded awful...didnt even sound like metal when it hit the ground when i dropped it.....all rust inside) but anywho. we put on my new pro series dual outlet muffler and it sounds really good. alot deeper than i thought. Next on my exhaust is replacing the old short tips with my new 4'' inch stainless steel tips.
