I need help in knowing what size of exhaust to buy. I barely got my Z went from Honda to Nissan I got a 90 Z32 TT and i plan to get a HKS Hi-Power exhaust but i also wanted to get test pipes but im not chaging my down pipes cause i still am rolling with stock turbos so what size do I need?

 

welcome to the site. please use the search function, and go thru rizz'z link page below before posting any questions. many of your questions can be answered there.

upgrading your downpipes has nothing to do with what kind of turbos you have. they will actually be one of the better mods you can do with stock turbos.

 

thanks for the welcome but i can't find the diamater of the outlet of the downpipe

 

if you look at all the vendors in the link, you will see that they only sell 2.5 and 3 inch downpipes. unless youre upgrading your turbos, you dont need 3 inch

 

true ^^^

but if you ever do plan on it, its better to buy prepared than spend the money twice.

 

thank you very much
