I could be wrong, but when my tired-old stock muffler came off last week, it sure looked like it had an offset/offset configuration, sort of like this:

…only flipped/reversed.

Here’s the MagnaFlow #14325 that AnalogVX used:

…which happens to have the exact same offset/center configuration as the cheap POS off-the-shelf Auto Zone special that I’m currently running right now (and absolutely hating the sound of).

The PV1 Cat-Back that Cyrk is selling has a center/center configuration… and here are some shots of his more recent (Killer!) center-in/dual-out setup:



I’m not trying to sound argumentative…
All I’m saying is that in the hands of a capable installer, as long as it’s pretty close to start with, there’s enough room under there to fudge things on the inlet/outlet configuration. --- An offset/center -or- center-in/dual-out Series 50 is doable.
