I have a small leak where my header is welded together. My exhaust guy said he's only seen a few XJ 4.0's that weren't cracked.
I was wondering if anyone here noticed a gain in MPG after a leak was fixed. I'd like to hear some actual experences.
I know I can spend money on a new header and fight rusty bolts half a day but prefer not to unless there is an increase in MPG.
My 97 4.0 doesn't appear to be running rich but have noticed a drop in MPG lately. TIA.....Al
