TR6 TR6 decision on header/manifold/exhaust

Hi all,

I have a 72 TR6 with pacesetter header + exhaust. It was installed by welding it together, and also onto the frame rather than with a hanger kit, and without the thicker gasket so it is right up against the oil pan. I do not race the TR6, but enjoy a bit of power all the same. Most of the time drive it 70MPH or less. I find it a bit loud.

I am having other work done that requires the exhaust to be removed. So I am deciding - and leaning towards a stock manifold and stainless steel double pipe exhaust system.. https://trf.zeni.net/TR6-250GC/index.php?menu=A&page=60

What are your thoughts on this? Other options I havent considered?
 
Famous TR6 racer once said the stock manifold is plenty fine
 
I am thinking of putting on a header too, so interested in people's thoughts, I have the later double pipe stock manifold from a later TR6 and a dual pipe, dual rear muffler system all (similar to the 4A system and the Falcon Stainless Steel Sports mufflers, actually I have the Falcon pipes from that system and fit my own mufflers). My system is pretty quiet, I have a friend with the pacesetter header too, and he is not so thrilled with it. I am thinking about the Moss Header they have on sale. Not trying to hijack the thread just any thoughts on best arrangements for a "fast road" TR250/6 would be of interest. I think Kastner or somebody did some dyno tests and a header and one big pipe back produced the most power, but that may be in a pure racing motor. My exhaust is like this one, but I didn't want to spend $120 each for the mufflers. https://trf.zeni.net/TR6-250GC/index.php?menu=A&page=63
 
I have been running the Falcon SS Sports exhaust for nearly 20 years and with a header for the last 6 years. It's much quieter than the Pacesetter set up but still carries a very nice tone. My ears don't ring after several hours behind the wheel, but the exhaust tone is still much fuller than stock. The header did add to the sound a little bit. I'm very happy with the set up. I had the Pacesetter for several years prior and loved it, but I prefer things a little quiter now.
The header wasn't just a bolt on ordeal. I had to grind the flanges to match up with the exhaust ports, though I did modify my head a bit. The butterfly clamps also had to be modified to offset the height differences between the the exhaust and intake flanges. There was nothing difficult to it.
It's also best to use the hanger set up available for the Falcon. You need flexibility at the rear to help accept the engine vibration. Otherwise, the vibration could cause cracking in the header.
 
I've have 6's with headers and honestly couldn't tell the difference. I had problems with the alignment and gaskets with headers. Wouldn't spend the money to change them out.
