Hmm, thats strange Rexpress, I have a full 3' S/S
TBE zorst on my Pig STi, it has the oval magnaflow muffler and I wouldn't call it quiet. I wouldn't say its VERY loud, but it certainly gets the attention of passers by. I haven't done headers or such. The zorst is an RMS system. (Norm Butler makes them though I think).
My system only has the oval muffler in it, no other resi's.
Cheers
