Classic 'zaust for Sti
 
Does anyone know if my JDM Sti ver 5 wagon can take any old classic system or downpipe? Is it a 3" neck or a 2.5"?

Should all fit, I had a MY98 saloon which when sold I removed the Scoobysport zorst, now acquired a STi6 wagon and the zorst is back on (well centre and backbox). The downpipe will be the same, personally I'd go for the 3" open-neck downpipe for the noise alone, but don't forget the remap if decatting! :D

I'd rather have a sports cat to be honest.

Cool! :thumb: May still need a remap with a freer flowing cat to stop boost spike....

Std issue will be 2.5 inch downpipe,mating up to the rest of the system,and as said above better off with a bellmouth type downpipe which will be 3' narrowing to 2.5 ' to mate with the rest of the system,all classic systems from 93 - 2000 will fit.
