I have a 1993 C-2 964 that has a stock exhaust system which has a cat by-pass on it'

I have heard people speak of a "G" pipe; what part of the exhaust system does it eliminate? Can you run a cat by-pass with it? I had the exhaust system off the car and was supervised at how heavy it is.

For the record I had my car smog tested with out a cat and it passed by 7 hydro carbons. A very small margin but it did pass.get

The goal would be to some additional performance and improve the exhaust note.

Any help would be appreciated
