What i want to know is what sounds the best on '91 Z34's. I am thinking prolly a Magnaflow or Dynamax etc. Help me out here.....stock mufflers are rotting fast

Are you looking for a full cat-back or just a muffler replacment ?

If you want a full cat-back it will run u between $400-$600 dollars depending on what mufflers you use and what shop does it. Get 2 1/2 inch pipe ran from the cat back to behind the rear wheels then y-pipe it to 2 1/4, then finish it off with either of these.

Don't forget to add a resonator between the cat and the mufflers or it will sound really rASSpy

If you want just mufflers then just buy something like the ones shown above in a 2 inch outlet and a shop would only charge you $50-$75
