Yeah I'm definitely planning on replacing the rest of the exhaust eventually. The idea right now is a custom single 3" pipe from the Y back. One step at a time... Hopefully with the right muffler/resonator combo it won't be too insanely loud.
Probably something very similar to
TypeOne's custom exhaust
Overall with this car I'm trying to keep a very lightweight theme. Single exhaust should save a few pounds and single 3" will give plenty of flow.
