What size gasket will I need for the manifold flange? Since it looks like they won’t need the original crush ring?
- Ezequiel
Hi Ezequiel, it would use a 3-bolt, 2.5" gasket. We do include gaskets with these as well.
Will these fit a na 2+2
- Zane

Will these fit with the auto transmission?
- Michael
Hi Michael, yes they do
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 ?
- Chris
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?
- James
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.
If these NA test pipes were installed on a 1996 300zx and the AIV bungs are removed will this cause the OBD II computer cause the check engine light to come on?
- CJ Dal Pra
The 96 does not have AIVs at all, but the 96 does have downstream O2 sensors, and with no catalytic converter and/or sensors removed, you would get a Check Engine Light.
Why are these double the price off twin turbo test pipes
- Aaron
Hi Aaron, these are expensive to make because they're hand-made, here in Arizona, and are not produced in the same volume as a lot of TT test pipes out there. They're more expensive to produce, but the build quality is also superior to most TT test pipes out there.
