993 Heat Exchangers on 964

[StanAE86]

I'm going to be trying to do the "flip the flange" modification to some 993 heat exchangers...for fitment on my 964. I have the exchangers and the cats off a 993 already.

I know people have done this, has anyone used the 993 cats as well? All the pictures I can find on the net (well, actually, only 2 or 3 pics), all skip the cats. I don't want to do that.

With that, does anyone have any pictures they can share with me, where they have cats and the muffler?

This is one company I know of that does these types of mods, but they don't have any pics using a cat:

Thanks.

Unless the local regs absolutely require the cat, I would leave it off and use, cat bypass pipes. The cat is very heavy and sits in a bad place for that weight. You will probably need some smaller custom mufflers and and pipes, I don't think that the 964 fenders are as spacious as 993

You will also want the 993 heat tube. Then run custom SCAt tube to the chassis heat-valves.
