i looked through the site,and i did a search for 300zx's and they sold Veilside kits.their instruction was to go to Veilside USA,get your price and multiply buy .85% and thats how much it would cost. also,they sell a fireball exhaust system for the Z for like @ $500.sounds really nice except the description says its a LH exhaust.does that mean a left hand exhaust system?single exhaust?
