Center section - HP/Torque gain or loss?

[Jim Griffin <JGriff@pobox.com>]

Okay folks... I've replaced the rear muffler section on my '92 100S (with V-6) with a less restrictive, better sounding aftermarket piece (Pacesetter Monza model), but I'm not sure yet if I want to go the next step and take out the center section (for an ever better sound... and maybe more performance).

I am seriously thinking of taking it out and putting in one of two things: another less restrictive muffler... or a glasspack, tube-like section (essentially, a straight pipe with perforations and some fiberglass for sound suppression).

Please offer advice on two things:

1. Sound - Will it be too loud... and will I, the neighbors, and the local police hate it?

2. HP/Torque - What will I gain... HP or Torque... or both? Will I lose torque at low RPMs? We all know that Audis don't have lots of low-down torque... so I don't want to LOSE any by doing this change. I vaguely remember that by reducing backpressure, you gain HP but lose torque (at low rpms... i.e from a standstill). Is that correct?

TIA... feedback is greatly appreciated.
