    I have read lots of postings relating to many of you switching exhaust systems but can you calify a few things for me.
    Are you all retaining your catalytic converters? Do you have two or four catalustics on your cars?
    I am assuming that you are retaining the converters otherwisw I think you would have to deal with the oxygen sensors being off.
    If changing to Tubis, are you running just straight test pipes or what? I have seen and heard of different types of pipes in addition to the tubi mufflers.
    What are you paying and where for the whole system of pipes and mufflers?

    most folks with tubis have simply changed out the cans. it's a bolt-on. nothing more creative than that - though some owners are changing out the central tunnel too. they're ridiculously over-priced for what they are. the tubi cans are basically just empty cans - there's virtually nothing going on inside them.
