RB Muffler for my 84 GSL - Which one?
I'd like to get a racing beat muffler for my GSL to cut down on the noise, it's got a really tinny sound right now with the Marcor SS muffler, and I'd like to get an RB one. A friend of mine told me that the first gen RB mufflers don't actually cut down on the noise as well as a T2 muffler, and don't sound very good. Is that at all right? Does the first gen muffler cut down on noise and make a good tone as well as the T2 one?

Banned. I got OWNED!!!
Well i know that there are two RB premaflow mufflers..79-80 and 81-85.. then i think that a GSL-SE RB muffler is a higher flowing of all three.
I have taken various RB premaflow mufflers from 79-85 and noticed that some had a larger orfice or exaust hole size at the tip. The larger one sounds and breaths nice on BP engines.

84SE-EGI helpy-helperton
The only differentiation between the RB mufflers for FB's is in the inlet pipe length and the number of bends that it has in it - there isn't a separate RB muffler for SE's, btw.
In fact, I took my 80LS RB PP muffler and had my rear tailpipe on my 84SE modified to fit the 80 muffler design. This was done to save some money from buying a new muffler just to swap it to my newer car.
In it's design, the stainless packed RB PP mufflers definitely help to reduce the 'tinny' sound of a rotary engine. Combined with the presilencer that they sell, the exhaust note is changed from the quiet stock muffler to one that really breathes better and has a much nicer 'character' than stock. I love the way my SE sounds between 3k and 4k rpm when you're accelerating hard, it sounds great. HTH,
