i need a recommendation on what cat to get.. i have a 98 4.0? i plan on getting a flowmaster muffler behind it

 

Same recommendation as above JSmith0055, I'm running open air filter, injector upgrade and a 2.5" flowmaster turned down before axle. Looking for a cat ( has O2 bung on downside) that would compliment this set-up. Do you have a 2.5" tail pipe also?
Thanks,
Scott

 

I need one for a 01 with a6 motor and I know it had pre cats can I do away with those I have some headers I'm going to be putting on and I have a megaflow cat back will I be ok by doing away with the pre cats and it still run ok give me a price I'm running stock size pipe or should I up it

 

Hey guys, check out this thread. I did my best to recommend the converters that are ideal based on the year.

what cat would be good for my 2001 WJ 4.0L?

 

Either the 608396 or 608226.

 

Too lazy to search .

2000 4.0L looking for cat and Magnaflow muffler combo.
Have to bolt on without welding.

Pls advise on parts and necessary clamps required.
Thx.

 

Cancel that!
Change that to a 1999 pls.

Thx.

 

Hey man can you help me with choosing a high flow cat for an 96 xj 4.0 HO OBDII O2 sensor one that will go good with your flow master exhaust system

 

I ordered a small high flow cat from performancecurve.com

 

How much for a replacement cat and O2 for 95 4.0? What muffler do you prefer that sounds good for an inline 6? Not like a rice burner
