Ti question

On a z06 exhaust are the cats and associated pipes Ti along with the mufflers?

Negative - they are stainless steel. Titanium for the rest of the exhaust system would be VERY expensive.

Thanks, someone tried to convince me the cat were Ti and replace mine to drop some more weight, no need

The muffler inlet pipes, from the H-pipe flanges to the mufflers, are also made of TI.

I thought the cats and the "H pipe" were one piece

That is correct.
The Z's, complete cat backs are Titanium.

Ok, so a Z06 has a separate cat that is Stainless, and it's connected to a Ti H pipe to the mufflers?

Ok, so the muffler inlet pipes that are welded to the mufflers are Ti, and the H pipe and cats are Stainless, got it. I always thought of the mufflers and inlets as an inseparable assy, so I called it the mufflers

Ok. so if I have changed the exhaust manifolds to shorty header and the mufflers to Z06 type (Ti), there is not much more I can do to take weight out, less taking out the cats which I can not do in NY, or going to a smaller cat for a marginal gain.

The factory H-pipe and cats are made of grade 409 stainless steel.

I really like the way this system sounds and performs.

If you are not bound be emissions, long tubes will be the best for power, sound, and weight reduction. I did shorties as a California car. No power increase (Dyno proven), minimal weight reduction (had factory steel manifolds, not cast iron), and no sound difference. Thats my experience with them.

Someone on here once said that only the 2001 Z06 had pup cats, obviously that was incorrect. Does anyone know what years and models had them? My 99 does not have them.
