I meant to check before I left home, but I'm lazy haha. What size catalytic and muffler do I need for my 93 XJ? I'm pretty sure my whole exhaust system is stock. I need to buy em now.

Thanks guys for looking out for us noobs.

I was planning on installing a flowmaster. That's why I just needed the size specs. looked in the "spec forum" didnt find it. are these Thrush Mufflers good? ...Isnt "thrush" also the name of an oral yeast infection?...haha

yep found it... https://www.google.com/health/ref/Thrush

 

think stock is 2.25"

you can replace it with 2.5" all the way to let more air flow through it.

 

That site sells Flowmaster too. Just type in what you want in the search box.

 

AWESOME. Thanks for the help.

 

Stock 2.25"

 

Wow this site (thepartsbin.com)has great prices! I'm looking at the super 44 delta flowmaster and it's saying it requires welding. so far I've managed all the work on my XJ myself but I'm ill experienced with welding. anyone know how much work is involved?
