My friend has a mechanic who will put on an exhaust system for like $100. So I'd like to know what size I should think about. (He has a 3" pipe on his 240sx and is very happy with it)

My freind just got his ZC in Sat. around 11:45 pm. Even w/ the new clutch and shifting slowly to break it in, it PULLS !

How come bigger exhaust is better for a turbo? I thought that smaller was better because it made the exhaust flow through faster and spooled the turbo up quicker.

It is more beneficial to have a larger piping b/c it will help the turbo spool up quicker, and help scavenge the exhaust gases quicker.

can you please explain what "scavenge" means, im lost on it.

Whay size do u reccomend for a trubo app? I am going to get a trubo but i have money to get my exhaust done. will the bigger piping hurt my N/A motor?

I would say, if you are going turbo in the near future you might as well get the larger piping. It will hurt your performance now in the low end, but when you get the turbo it will be more beneficial.

Scavenge=disperse, get rid of.
