Exhaust for nissan 300zx n/a?

I have the HKS Hi-Per Cat back exhaust on my 300zx Twin Turbo. I love it, it has a unique look with the dual angled mufflers. Check out pics.

Other good ones are Stillen and Billy Boat,

They will all add about the same HP (which isn't much for the n/a) so just check out pictures and see which one you like the looks of the best. I can say that both the stillen and HKS are quality exhaust systems.

If you wan to increase power i would recommend headers as well.

In order to make the twin turbo flywheel turn in the NA transmission you may need to grind down 2 or 3 mm several places where the bolt bumps are. Your radiator and A/C condenser is to wide to pass the turbo boost pipes and blow off valves plumbing inter cooler. Almost all owners get carried away and want 400+ hp. Electronic boost controls JWT computer and Exhaust down tubes and cat back systems and modifications all cost plenty. Some parts are obselete and others are almost impossable to find any more. A front Clip might have many parts you will need. Like a Bumper cover with gill slits for intercoolers. And boost pipes. Good Luck

If you want quality go with the HKS or if Stillen still has a system there system sounds good too.
