Were to get Exhaust Heat shield?

[MacinTek]

I'm referring to the one on the driver's side. Mine disintegrated and DMC is out of stock. Any suggestions?

[Delorean Industries]

Are you talking about the converter shield?

Do yourself a favor....just get a dpi exhaust!

Great... then I'll never pass visual smog inspection in the People's Republic of Californicate.

Why not? I still have cats and o2 sensor. What else is required?

[Delorean Industries]

We have never had one of our systems fail the left coast. Meets all efficiency tests.

I've got the DPI exhaust on mine. Salt Lake City is pretty strict (I had to get a catalytic converter put on my CRX when I moved there, which I didn't have when I lived in CA) and my D passed emissions with no problem.

The problem isn't the Catalytic Convertors. It's the exhaust manifolds not being CARB-approved.

You can run an emissions test on one of these exhaust systems, and it'll pass no problem. BUT, when it comes to the visual inspection, the shop will know that it's supposed to be a single-exhaust/catalyst system. So then they'll go looking for the CARB exemption number. It looks like this:



When they don't find it, the car automatically fails. Even though LAMBDA is still in place, the Catalytic Convertors used are CARB compliant and approved specifically for the DMC-12 application, and the car *will* pass smog if they proceeded to test it. Hell, it could not only pass by being well below the emissions levels, but it could run cleaner than stock with more efficient cats. Doesn't matter, they'll still fail the car. So you've got to hope for a smog check station that's weak on the visuals.

But that's California. Over the border in Nevada, they'll exempt you from testing entirely with a yearly limit of 5K miles (engine/exhaust mods allowances vary for sub-Classic classifications). Pre-OBD-II daily drivers can completely rip out stock exhaust systems so long as there is a muffler and a catalytic convertor working on the new one.
