Guest CS_280ZX Posted November 28, 2002 Share Posted November 28, 2002 Hi All, a question regarding an exhaust line upgrade/ mod my current exhaust line is the original supplied with my 1979 280ZX, but i have been considering a new exhaust line, muffler etc. to give it an even better idle rumble and nice growl when driving. any ideas for a specific model or type to reccomend ? Cheers Carl. Quote Link to comment Share on other sites More sharing options...
80LS1T Posted November 28, 2002 Share Posted November 28, 2002 Well when I had my L28 in my 80' ZX I had a 6 into 2 header with 2" to the cat then 3" to the back where I split it in to 2 pipes(for looks). It sounded like a V8 at idle but if you dont insulate your car for sound it gets kind of noisy at 30mph+ and I doubt that its even close the the legal limit for noise. I ran that for about 1.5 years with no problems. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted November 29, 2002 Share Posted November 29, 2002 I don't know what kind of emissions requirements you have in Australia, but I would and do run a header and two and a half inch pipe and a turbo muffler. My car produces a throaty very healthy rumble. Too large of a pipe diameter reduces exaust gas velocity resulting in a loss of horsepower.
