Will these fit with the auto transmission?
Hello will these test pipe cause my check engine light to pop up and make passing smog not possible ? Does it remove the catalytic converters ?
Hi Chris, these will remove the cats, but on the 90-95 the cats are not monitored, so it doesn't throw a CEL.
So just to verify, I have a RHD JDM 2+2 Twin Turbo 1993 300zx. The NA test pipes are the same as the JDM Twin Turbo?
That's correct; it's really the US Twin Turbos that are the odd ones out. It is worth noting, however, that virtually all aftermarket downpipes are based on the US versions. So if you were to run aftermarket downpipes, then you would need to run US TT test pipes with them.
