I was thinking of perhaps sticking a Mondo exhaust system on my '79 280ZX 2+2- will I actually notice a difference? Also, are there any legal problems associated with the swap (I live in CA). Thanks a lot.
No legal prob's in CA if you go from the cat back.
It made a HUGE difference on my 72 when I went to a 2.5 system, but that was also one half of the factory Y was 1/2 way blocked by a poor weld inside the factory manifold.
I put a Motorsport Auto 3 into 2 Header on mine and a Monza Exaust system from
Victoria British. Both were a MAJOR pain in the ace to put in, but it sounds, and
drives excellent. I have noticed a big differance in power output.
