I have a standard 280ZX and I dont plan on making any engine mods. I've heard a 2 1/2 inch exhaust with two mufflers is the way to go with the 2.8 litre EFI engine but my local exhaust shop believes this is too big for an engine under 3 litre. They recommend 2 1/4 inch system, but what do you guys think. I like the 2 1/2 inch system but I dont want to loose power in a car thats already 22 years old.
The stock exhaust manifold looks fairly effective so is it worth paying the money for a set of headers (extractors). When you installed a set of headers can you keep the standard heat shield, as I dont want to remove mine. The exhaust and inlet manifold gasket is all one piece, therefore if I decided to install some headers do I need to pull the inlet manifold off to replace the gasket or is it normally ok, to just bolt the new headers on using the old gasket. With other cars I have owned I have always replaced this gasket. Any help would be great.
