With 96 and 97 and Cali you can forget mid length you are pretty much limited to SLP Shorties, the cat on the drivers side is quite specific

With the drivers side cat having to stay in the stock place all brands of mid tubes are going to be jammed up on that side. It's a bad situation. I'd suggest looking at what all the manufacturers offer for your car and picking the ones you like best. They're not much better than stock manifolds.

Lol at all the mid-tube header haters....just get some pacesetter mid-tubes I have them on my 383.....they are 50 state legal. They have plenty of clearance for lowered cars and the ceramic coating still looks brand new on mine 3 years later. They sound good as well; a BIG improvement over stock manifolds sound and power

I ran Pace Setter's mid length headers on my 96 Z28. Get them ceramic coated; they are very high quality; but much harder to install than the long tubes..!!

My appologies; I ran BBK mid-tube headers on my 96. The pace setters were on a different car. The BBK mid-tubes worked with the factory y-pipes and cats. Mine was a dual cat LT1.

With dual cats, the driver side pipe comes up too high in the engine compartment to get anything other than shorties, I would imagine; it just doesn't leave enough room. Probably your best option is to save up and do LT's and custom Y pipe, having some aftermarket cats welded in. IMHO

Good luck getting away with "non-stock" located cats in California, the emissions **** state. I would just find a crooked mechanic to pay off

For real the only way around it out here is shorty headers or go lt's and find a smog guy who will overlook the cats being moved. You can still get lt's with emissions hook ups. Otherwise, stay stock.

I don't live in CA so I don't know how strict shops are. You'll have to find the catalytic converter law, but I think it says that the factory cat has to be located within 3 inches of where the factory put it.

Is it possible that you could install mids and modify the factory y-pipe within the 3-inch limit and at least gain a little power and still pass in CA?
