The x-pipe for the ABH is a convoluted affair, physically it felt lighter, but diameter wise, connecting bores are pretty much the same.
I sold it to a guy keeping his ABH car original.
The cat pipes are the same diameter entry, ABH or PT. exit is 55mm o/d on the PT, and 60mm o/d on the ABH. Cat temp sensor connections are in slightly different positions, and types of connection.
The original PT cats were emptied of their broken contents. So they are now straight through, unrestricted.
Again, I sold the cats from the ABH setup as they were in useable condition, and I don't need the cats. The chap who bought them was in dire need, as his X-pipe and cats had been seriously messed with.
I then used the joining sleeves from the old PT exhaust to couple up the different diameters. I shall fit a full stainless system later, anyway, so selling those parts mitigates the cost of buying the donor car somewhat.
I reused the original PT headers for now. Keeping the ABH headers for later. There didn't appear to be any great difference, save for the flex section in the ABH left header.
Not perfect, but it works well. And now it has the much nicer tail exits of the ABH. And a more glorious note. I'll be sad and geeky and youtube a video when it's all back together fully.
