Ok for exhaust i am planning on going with something other than the huge 3.5+ circular tip, i am trying to find a smaller diameter, but this is going on a turbo'ed car which limits my options. But i've thought about the pakfiefer rear with this style exhaust:

But i don't know how it would look, anyone know of any similar style cars with oval exhaust, Only reason i am choosing that one is because of the larger diameter would be better for flow for the turbo.
