Exhaust Diameter

Does anyone off the top of their heads know the diameter of the exhaust on the WJ 4.0L. I think it is the same with the V8 as well. I think but not sure if it is 2.5". Im looking to put cutouts but make custom ones.

Re: Exhaust Diameter

That is WRONG. I went and bought parts thinking he was right, and it's not. It's actually 2.25"

Re: Exhaust Diameter

It doesnt hurt getting a bigger diameter for exhaust. It can be welded on.

Thanks for the info. So what did you do get a reducer or exchanged it for 2.25 hardware?

Re: Exhaust Diameter

The stock piping for a 4.0 is 2.25, my magnaflow was 2.5 and I got it welded without any sort of reducer or connection, one of the messiest welds I've seen and I do not recommend doing that , if anything if it ever breaks either I'll fix it or change it to 2.5 or 3 inch piping.
