Getting ready to replace the entire exhaust system on my 2003 Z06. Has 21,000 miles on it and in perfect condition. I regularly see the factory titanium cat back exhausts selling for $400 to $450 on here but I don’t see the H pipe or manifolds for sale. Is there any market for the entire system or should I trash the factory manifolds / H pipe and sell the cat back? If there’s a market for the whole system, what would be a good asking price?

If you have the space to store them keep them, they may be needed to smog the car when you sell it (if you ever do).

I haven't had any interest in the stock manifolds from my car. I think occasionally a set will sell if the right person is looking locally, but they really aren't worth shipping.

The H-pipe is kind of the same way and even harder to ship due to size. I personally took mine to a local metal recylcer and got around $150 for it, mostly for the cats. If an H-pipe does sell on the forum, it's usually around this price, so it's easier to just take it to the recycler than wait around for a buyer.

There's not really much demand for the H pipe and manifold.

I guess I’ll keep them and the AIR system crap just in case

The 2002-2004 Z06 H-pipe is a mild upgrade for I believe 2000-2004 non-Z06, and 2001 Z06. This is because it's a less restrictive single-cat (per bank) arrangement vs having 2 separate cats.
