    I have a 1994 Canadian Spec 348 Spider. It appears to have factory straight pipes (with the O2 sensor) between the headers and exhaust, and it has the Tubi exhaust system. Sounds great. No Cats.

    Can anyone tell me if the Canadian spec car was different that the US spec (i.e., did it come from factory without the Cats) or is what I am looking at a straight pipe inserts part of the kit from Tubi?

    Also, what is inside the Tubi (baffles or glass pack wadding??) and can they breakdown over time thereby changing the backpressure?

    Any ideas?
