I just got back from the local exhaust shop today in southern california, and got my resonator removed and replaces with a straight pipe. Just a tad louder and adds more rasp and crackle/pop im really happy with the results and going to use it for a while until i save up enough money for a nice catback system. This is probably the best, and cheapest no brainer mod for the R50. Only $40!! What do you guys think?
