VW Baja ROTARY install

I should have been more clear about that. What I should have said was I briefly tried the RE glasspack on the 20B and it quieted it quiet well. Before then it was situated in a dual pipe exhaust system, along with a few other RE glasspacks, on a rotary truck. Some glasspacks close to the engine lost some of their packing while the ones further away survived. This glasspack was in the middle and it survived pretty well (its mate, installed parallel on the other pipe, was not as fortunate and is louder-ish on percent's 7).

I expect it to keep the baja's 13B at a reasonable volume level for a while and I'm counting on the u-bends to take some of the bite out of the exhaust pulses, like how a turbo can tame rotary exhausts allowing the use of less restrictive straight through mufflers like Borla in the cat location close to the engine, without causing a droning or otherwise excessive and unpleasant noise levels, as would occur in NA form if not for 'presilencers' and the like.

When you've heard as many rotaries as I have, you honestly start wanting a quieter system after a while. It sure will be great if the small glasspack survives as well as the big one has so far.

I have a feeling this system will sound decent. I'll have to get a video or something once it's running. Gotta break it in first, of course.
