So I've been searching and I can't find the answer so here we go:
What is the model # or is there a model for the Doug Thorley "Jardine" cat back for the dual cat 3rd gen? I found the model #89215 but its listed for 1996-1999 I'm assuming because it is for the single cat systems. I live in TX and we do not have emission regs so I was wondering if I could convert to a single? I've never done an exhaust (except for my bike) and really like the look and sound of the Jardine systems. So, can someone show me the thread or answer this question for me?

Reference: I have a 2002 4wd SR5 A/T with the 3.4

 

Jardine sounds good, It seems that people who have it are very pleased with the tone.

I converted mine to single cat with an O2 simulator. It's fairly easy to do.

 

I have the Jardine kit for my '02. It's part #89218. IIRC, Doug Thorley isn't making these kits anymore, but you still might fine a new one out there somewhere. Pretty nice sounding system, but be sure to install a thicker gasket at the front end of the system. Search Jardine and you'll find the thread.

 

I like mine just fine, nice growl to it. I second the gasket recommendation.
