Looking to replace exhaust from manifold back. All the direct fit catalytic converter sets I see appear to come together at and run down the drivers side. I have an 09 JKU and my exhaust runs down the passenger side. Can anyone recommend a kit or source to buy the one I need.
 
Interesting, my 09 JKU runs down the drivers side. You would think they would all be the same. I got my new cats on eBay for about $230. The quality seems very good and my Jeep runs great. Also haven’t thrown an O2 sensor code since I have had them.

if it’s the same layout just in reverse, I would recommend finding a 2 piece unit. Easier to install

The cats you got off ebay, are they standard or highflow/performace cats?

They should state in there add if they are OEM or high flow, I have high flow on my JK just had to put O2 sensor foolers on.

Yeah righto, seems to be a common issue with doing a full exhaust. Seen better power or fuel efficiency?

Don't really know the exhaust I had to replace when I bought it someone tried to do a dual exhaust and had exhaust leaks all over.

Didn’t realize was there was an area in CA that didn’t require a cat?
