I am looking for best short tubes for hot rod cams.
I have long tubes cats delete, it sounds great but smells bad in my garage. I need good hot rod sound with cats.

I could be wrong, but I don't think the cams matter to the headers or vice versa.

You don't like the classic muscle car smell? I love that smell when I drive behind one, but probably wouldn't want it in my garage either.

Why not get a catted mid pipe that works with the long tubes that you have?

As far as I know cats will not work with my off road long tubes, cats needs high temperature. Hot rod cams sounds better with long tubes, you can hear longer pulses from each cylinders.

I'm running long tubes and cats, it works pretty good for me. There is only a slight smell at start up. I will throw a code every three months or so, I just clear it. I live in an area where there is emissions testing. I have no problems passing. Have you ever thought about switching to more of a mid-tube design like Kooks, Pypes, or Mac; then get a catted matching mid-pipe or splice in the cats?

If all you are concerned about is the smell you might want to try some Magnaflow spun metallic cats mounted as close to the headers as you can get them. When I had my 85 it used to stink up my garage terribly and the scent would come in the house if I closed the garage door with it in there still warm. I put a pair of the Magnaflow cats right before the crossover on the off-road H pipe (not optimal placement but the only place they would fit) and it cut the smell by probably 75 percent and didn't change the performance or sound at all.
