So the cat was already deleted when I bought my "98 XJ just a few months ago. When I had my Flowmaster put on they just replaced the straight pipe that was in place of the cat because the piece that was there was a POS weld job. I just lifted the jeep with a 3.5" RE and it's sitting on 33" 12.50 km2s. Just got my gauges fixed and found out I'm getting like 9mpg! So I am going to replace the spark plugs and the spark plug wires tonight in hopes of upping the MPGs. However I was wondering if I put the cat back on and put the 02 sensor back in place if this could possibly help up my MPGs? I'm running stock gears which are 3.55s. I've read threads where several guys are still getting 16mpg with 33s and stock 3.55 gears. If I can get 16mpg I'll be happy. Already replaced the air filter btw. Any other ideas?
BTW I really like this cat: http://performance-curve.com/425250-25catalyticconvertero2.aspx
