I'm confused. Mudfrog recommended part # 425250 (on his site, performance-curve.com) for my '99, but my O2 sensor is downstream of my cat, in the straightpipe between my converter and muffler. Does it matter?
I'm pretty sure its plugged or getting there and near-future plans include a full exhaust upgrade, so I'd like to get a high-flow. It has a Chrysler logo stamped on the bottom, maybe the original?

Ok. Question time. How bad would a side dump sound on a flowmaster 44. Also if I did that, would adapting the output to 2.5 in or even 3 in. Change anything?

If you want deep chambered mufflers aren't so good on these engines... non chambered (fiberglass packed) muffler will be less raspy.
