Re: FYI on exhaust systems

do you think that the stock catalytic converter is more efficent than the ones that come on the MRT h pipe. i was looking at the Maxflow MRT o/r h pipe. and its only offered 'without' catalytic converters. so does that mean if i buy that h pipe will i have to use the converters that are currently on my car? and will this MRT o/r h pipe system hook up to borla s type cat back exhaust without complications?
