I have a 91 integra that i plan on boosting. I ordered a maganflow cat 2.5 and magnaflow muffler 2.5 and having a muffler shop make me an exhaust. My question is do i need a resonator to pass emmisions? I need to go in 30days and i dont have a stock exhaust

yes and no... if i remember correctly you are out of CT, so im not sure of the exact laws there... BUT... here in CA (im sure the laws are worse than yours) you don't need a resonator to pass emissions.

OTOH, i would suggest putting a resonator in only because the rasp is incredibly annoying. The only thing that would make your car illegal w/o a resonator is the noise factor.
