No pretense whatsoever. Compared to the Geo Metro I was driving, the Z is already a performance vehicle. I do need to do something about her exhaust though because it appears to be off a later model and the flange shape does not match the manifold. The muffler is also in bad shape. I am getting exhaust smell in the cabin which could be from the mismatch, the muffler, or the really leaky rear hatch seal. Beth

Hello, I am brand new to Z-ownership and am needing to do some work on the exhaust system of my 76 280z. I read most of the posts in this forum and am now more confused than when I started. Most of the time the Z will be my daily driver and my driving style is not very spirited. I am wanting to make sure my mods do not negatively affect mpg. Also I do not need Daisy to be terribly loud. What are the major differences between the 6 to 1 headers and the 3 to 2 headers from MSA? I think I read somewhere that the 3 to 2s were better for lower-end driving and read somewhere else that there was no proof of that. Any input or recommendations would be greatly appreciated. Thank you, Beth
