alright I have a 01 zx3 with iceman air intake and magnaflow cat back exhaust. I have a focus central flexpipe ordered but it is on backorder. Should i wait and get everything at once and put it on at the same time to finish out my exhaust or what? it would be a while before i had the money to finish it. Should i cancil the order and get like a steeda short throw shifter or what? also would the flex pipe with just the cat back exhaust make it any louder and would i be able to tell any differance in power without the exhaust complete.thanks also is the 25.00 ebay short throws any good or not?
