what are the pros to this? Im thinking about putting the vibrant 1149 eithor 3" inlet to 3'' dual tip with a new Y pipe that goes into a 3'' downpipe instead of the stock one that goes into eithor 2.25 or 2.4 i cant remember witch. i dont know weather to get a high flow resonator, this guys sounds really nice http://www.youtube.com/watch?v=3yIeIjUJfeQ
But i also am thinking about just stock Y pipe and just putting a straight pipe to the muffler no resonator, this sounds real good also but i dont know if theres a power increase from no res or fatter pipes. any suggestions??
