Exhaust/header options, Is there power to be had? Options

[blaize]

So, I have a 73 2.0. it has stainless heat exchangers on it. looks like they are 1.7 pipes. I bought a new rear bracket (2.0) and it does not fit. looking at pictures in the books I have it appears I have 1.7 exhaust. did these come stainless from Porsche?

I have a stock 1.7 muffler on it, is bursch the way to go? I would rather retain heat as this will be a year round street car (mabye daily). but what are the options. so whats out there and whats worth owning. I saw one setup that was 2k for headers and mufflers w/a heat exchanger on one side. Very nice but way out of budget.

As a side not anyone need a brand new 2.0 rear exhaust hanger. I paid 40, take 20. It is new from AA. I happened to be in Atlanta and stopped by. you guys are right, rude , condecending, and what a dump. I would gladly trade for a 1.7 in servicable shape.

I had a nearly one inch descrepancy the first time I assembled the exhaust / heat exchangers. I had tightened down all the head studs first, then went bolt up the collector. It wasn't even close. I had to loosen the head studs, loosely assemble the muffler collector, then progressively tighten everything.
