This TJ has everything. 4.0, hard top, tilt, cruise, auto, leather interior, yadda yadda. I'd be surprised if it didn't have an HO engine. I'm a co-founder of another Jeep specific site and we have a VIN decoder so the guys can get more information on their Jeep's. Is there one for these Wranglers? Also, I have a bad exhaust leak. Could be a loose flange, cracked tubes, I dunno yet. One shop quoted me over $800 to replace BOTH headers. Does an '04 TJ with the 4.0 have two manifolds?!
