According to the SRT6 service manual, Exhaust section, Section 11, page 3. (11-3).

here is the page in question. It DOES mention a three way catalytic converter. Although the picture shows two separate converters and a dual pipe back to what looks like the main muffler.

If your system looks different (take a picture), then there is some serious descrepencies between the SRT6 service manual and real life.

Let us know!
