if i get this stock WRX downpipe, will it bolt up to the existing stock exhaust? i dont wanna buy it and not be able to bolt it all up myself. also, i have the stock NA cat and catback on my car... is the diameters going to be different to where i cant bolt them together?
the stock wrx downpipe will fit on your turbo fine, it has the same flanges as the TD04, but i'm not sure if it will bolt up to your NA cat and catback. it would be worthwhile to just get the whole wrx catback then have someone make you the extension that is needed. hope that helps.
yup.
