give that trimill a chance,,going stock VW is quiet...maybe A1 has something, my A1 was deep and throaty,sounded like a sports car..
someone will chime in here..
With my engine setup the Tri Mil sounds more like a harley motorcycle and I would like to mod or swap for more of a deep purr...
I had the same issue with the Trimil. Swapping for an inexpensive single-outlet muffler was the first change I made to my car -- in a hurry because I was concerned for the neighbors (especially after the car had been delivered late on a Sunday night). I also found a badly sealing gasket on the Trimil as I took it out, so mine may have been worse than yours. I am not focused on maximum power so you may spend more time shopping for equal length pipes than I did. See comparison photos at https://www.flickr.com/gp/farsightful/b744S9
What is the exhaust you put on and how did it affect the sound? I really love the look of the dual chrome tips, so that may not be something I can step away from, which is why a mod could be an option for me as well.
Amazon part as quoted below. Sound is still raucous, not a purr, but loudness reduction was in the significant-to-unbelievable range at 10 db (80 down to 70) based on Sound Meter app from Google Play Store, with phone sitting waist-high, 10 ft behind the car and centered, closed garage, 2500 rpm.
@Sacto Mitch video sounds amazing and has your preferred dual tips. I should look again at the price of that. Look out for alternatives that require the exhaust be removed to adjust the valves -- that took at least one alternative off the table for me.
If you go exactly the way I went, note you have to modify or replace the rear engine tin to clear the intake manifold heat risers that the Trimil doesn't have.
Have you asked @Alan Merklin or his engine-builder for his quieter-muffler thoughts?

Brain fog , I'm not sure if that model Tri Mill has baffles built into the tail pipes, if not no reason why a slip in motorcycle baffle wouldn't work.
I like the one @Sacto Mitch has, but it is about $650 shipped from Taiwan, so I would probably want to hear it in person first.
Funny story. I was driving around my extended neighborhood tonight testing a couple things out and a guy came out in the street and flagged me down. He said the car was beautiful but didn't sound right at all. He then proceeded to show me his 356B that hasn't ran since 1983 and his working 914 in his garage. It was great talking about the history of both and how he wants to get the 356 to turn over. Really great guy I would never have met without my plastic car. Now I have someone local to test my vw engine to porsche sound when I adjust the exhaust.
