quietest single muffler available
I have a 87 t2 with a full racing beat exhaust. I love how its quiet. I know a single exhaust won't be as quiet as the big resonator and 2 main mufflers, But I was thinking about keeping the rb resonator, but going single 3" the whole way back. Who makes the quietest mufflers, racing beat? Can I even buy just mufflers?
Anyone know if there will be any performance gains from going single? I have a street ported s4 engine with a bnr stage 3

I'd be worried about boost creep...
but other than that I'm literally doing the same exact thing. You'll need to be careful because rotaries have a habit of melting what most mufflers are packed with (fiber glass mat)

i've done a few FC's with the RB center muffler, and a custom catback, and they all stay quiet enough.
the RB center muffler, does most of the silencing, and the rear muffler controls most of the tone.
the best sounding one was an RB center with a borla on the end, it sounded like a race car, but volume was totally fine

the sound of the RB power pulse cans for an end of system sound reduction have a quiet yet deep tone to them. add a turndown and it is my preferred choice.
an XR-1 would probably work well for a mid system deadener since it doesn't muffle quite as well and leaves a little of the sharp Db's in place.

Aaron, what was the brand of presilencer you used on your car? I forgot the name but I remember you can find them at a reasonable price on summit racing.
