Exhaust Recommendations for a '73 .20 Options

[DC_neun_vierzehn]

A Bursch exhaust came on my '73 2.0 when I bought it a couple of years ago.

I always thought it was a bit loud due to an exhaust leak I had (thanks for a both a stripped threads on one of my heads and a broken dog ear on that heat exchanger.

However, now that the motor has been rebuilt (new heads) and new heat exchanger has been installed and all exhaust leaks have been addressed, I'm still finding it too loud.

I recall reading that there were quiet Bursch systems and loud Bursch systems. If that's true, I suppose I have the loud version. It's a bit much for what's basically a stock car (the engine was a 2056 rebuild).

What's available out there new (or used if in great condition) that would be quieter, but not sound like a VW bug.

The 4-2-1 piping is what counts (in my book). I replaced the muffler with a similar sized but quieter one. I think it was from Edelbrock. New muffler gaskets too.

Can you dumb this down for a newbie like me? What is 4-2-1 piping?

2 pairs of primaries merging into 2 secondary pipes that merge into a single pipe that goes into a single entrance muffler.

The original exhaust was 2 pair of primaries directly connecting into a complex muffler.
Different versions/manufactures might handle the inner flow paths differently.
It's not an open log internally.

If you had all 4 primaries go to a single collector, you would call that a 4-1. My old school Bursch in like this.
