I have spoken to raceonly about the aes mufflers and they swear by them, shipping is expensive these days! Im surprised that some American companies are not building solid rotary specific mufflers in different sizes and inlet/ outlet configurations.

So far it's seems that AES mufflers and SP mufflers are the sweet spot

Has anyone tried the Racing Beat universal mufflers? They seem like a great muffler and Racing Beat has been in the industry forever!

Im hesistant to buying and hating, I would mind it so much if I hadn't already spent a lot of money on the car recently!

Borla makes a rotary-specific muffler, readily available in the US.

I have a Racing Beat 3.5 in. universal muffler but have not used it. I was planning to run 4 in. to the rear then 3.5 in. out the back. The RB universal muffler is 14-in. long which is leaves a lot of room if using for a rear muffler. I like how Burns or AES will build you whatever length muffler you want in a couple of diameter options.

I've been seeing the first gen guys complaining about the newer mufflers from Racing Beat are not as quiet as the older Italian made mufflers. The RB catback I bought for my first FD back in '97 was quieter than the newer one I have from around 2015 but both are quiet.

I've heard that oval mufflers are quiet, which makes sense with the OEM, Racing Beat, and SP mufflers top choices for quiet.

ive got a FEED system on my FC. its what i wanted when i was a kid.
its 94mm pipe (3.7"), and pretty quiet for what it is, lots of low frequencies though.

it has a mid muffler and a rear muffler. the mid muffler is pretty small, its about the same as the RB 3.5" center muffler.
the rear though is the biggest thing that will fit in the car, its 200mm (8") diameter and i think 500mm (20") long?

they are both packed really tight with something too, if you knock on it, its like granite
