just bought 1999 z24 with 150 000 km. i want to do just intake and exhaust, what do you recommend. I have a 2001 Cavalier for my winter car with 226 000 km, been an amazing car, its stock except for cheap cherry bomb exhaust, i ordered a cheap intake for it off ebay from chromeintakes, i've heard they are alright and i've heard they suck, for how cheap they are, anyone have one on a 2200 ? i know its lame but its just my beater winter car.

the intake does'nt matter, just make sure you put a k+n filter on the end of it. buy a cheap ebay one.
the exhaust really depends on what kinda sound you want, ask around other members what kind of exhaust set up they like. see if you can get sound clips. and welcome to the site man! check out the performance forum for your exhaust questions. read the faqs first.

Basically, whatever you get for exhaust youre going to need a resonator welded in the middle to cut down on the raspiness.
