Modified Exhaust?

[mbaz]

My exhaust runs two pipes passing thru two cats and entering into a single muffler and out one tailpipe. It's all 2 inch pipe. Might this be stock, it's laid out differently from my repair manual and uses 4 O2 sensors (1 ea before and after the two cats), also different from my repair manual. Anyone else's exhaust set up like this?

That's stock. Plus, I think it's 2.25". Welcome to the site!

I'm pretty sure it's stock.

Sounds exactly like mine. I'm not so sure about the 2 O2 sensors after the cat though. I don't remember any being after the cat. I haven't looked underneath it yet, but couldn't find any pictures showing the layout. And yes it is 2.25".
