hey guys, i just installed my Dynomax cat-back on the 'maro and all i've got to say is...if your not runnin' some type o cat-back, save up dat cash and do it! next comes the open element, B&M Megashifter, and AFPR. (now that it dawns on me...if the cat-back feels so damn good...i cant wait for the headers and y-pipie!)
