hey i got a dc2r and just got my new Mugen Twinloop and just want some suggestions on the question i ask.. I got a full exhaust system from headers to axleback and there is an exhaust leak somewhere from the cat to the headers.. took it to liverpool exhaust and changed the gasket but still the same leak noise. It doesnt sound right when i drive at all, could it be having a blown out cat or somethings wrong with the headers.. give us your thoughts.. cheers
