05 GC Hi-Flow Cat

I have an 05 Grand Cherokee with the 4.7 engine. I have some performance mods installed already but I was wondering if there was an aftermarket high flow catalyc converter. Also I was wondering if there was an under drive pulley available for that engine?

Re: 05 GC Hi-Flow Cat

May want to check the part numbers on the ones you have. If they're the same as the ones on the Hemi's, they're already high flow......according to the exhaust guy that built my complete header back system. I specifically asked him if they needed to be changed and he said, no, they are high flow wire spun (whatever that means) cats. All that being said, I have JBA headers and high flow cats. on my Hemi LX. Maybe they make some that will work on the WK's too. May want to check with them too.
