Deciding on a muffler for the Cosmo POS :)
I think I have decided on a Borla Xr-1 Race muffler, 3" in, 3 inch out, all stainless for $159 Anyone else have experience with something else?

I don't know about the Borla. I haven't heard it.
On turbo rotaries, I have heard both
Dynomax and Magnaflow. The Dynomax was very quiet, the Magnaflow sounded sportier.
I will be using a Magnaflow, similar to MoreMazda's exhaust in his recent thread.

well, it shouldn't be that loud, should it? i mean, are you planning to use some sort of presilencer? i know that the turbo will muffler a lot of the sound, but i'm just not sure if it will be enough so that it will be "street-friendly", you know? 
and i think Borlas are pretty good, especially the XR1 line ... my friend uses it on his Corolla (with an REW in it).

Nonononononono... that is LOUD
And i mean redefining loud. I built an exhaust using just one of them 'muffler' thingies from Borla (
), and it's LOUD. It sets off car alarms at IDLE, and gets MUCH louder than that when you step on it! This is on a 1990 TII with (at the moment) a stock turbo. I have some sound files here in case you're interested in how it sounds...
