aftermarket muffler drone, returning to stock

Hi Eveyone, lurker with my first thread here... 97 Boxster, 5 speed

Aftermarket exhaust w/equal-length headers, high-flow cats, twin tip muffler. Don't know the mfg, but the quality is decent.
However, bad exhaust drone due the muffler design.
Would like to return to stock starting with the muffler, have a couple questions...

What is the distance inlet to inlet on the stock rear muffler?
Trying to gauge if I can fit the stock muffler to the existing setup.
For reference, the distance on the aftermarket muffler is approx 28".

Lastly, is the 2.7L or 3.2L rear muffler a better choice compared to the 2.5L?
From what I've read it appears so, but I'm not understanding why they might be better.

Thanks in advance!

Loving my Boxster.
