My XJ has a RE4.5 lift 1st off. I travel 4+ trails often. I noticed that the down pipe has a large dent in it caused by some part of the left upper control arm hitting it. Has anyone else had this problem and is there a fix for it? I haven't had any luck in the search area. I'd like to replace the pipe to help the mileage but need to track down the fix first.

mine looks the same, about half dented in, my buddy always said it must have been a rock, yet it's so far tucked up in there,
then i realized the front driveshaft wasn't stock

SPOBI. Stock dent just after the collector on the factory header. The factory made it.

As seen here on my junk too. Yours look the same?

Yep - done by factory to improve operating clearances for the front driveshaft. Not much to be done about it. Yet...

Not yet. I do plan to talk to an exhaust house about the possibility of using an "oval" pipe there, rather than round, to give the same flow cross-sectional area, but also give clearance for the front DS in articulation...

yep call Pacesetter and order there header/downtube kit. Replaces the manifold with a true longer tube header and down tube with mandrel bent tube sections all the way to the Cat, eliminating the factory set-up completely. All for just under $250 shipped to your door.
