A few years back, I recall seeing some pics on Kolak's site about a mod to fix the "pinch" in the downpipe on the XJ exhausts.

Well, that info seems to have vanished as he revamped his website.

Anyone know if someone sells a kit to replace that pinched pipe or if I would need to have something custom made up to replace the pipe?

Thanks!

What IS up with that pinch?

just order a new walker front pipe

Is this an OE replacement w/out the pinch? Part number?

Answered my own question.......


Walker part number 55277

would you really gain any real performance from removing that small pinch?

ha i was just curious if its even worth it, we need feedback!

I replaced mine when it rusted out. Not much, if any felt gain, but I also lost the cat which is suppose to help flow as well. If I get her road-ready I'll put the cat back on, but for now she's a trail rig.

I did notice the truck ran a bit smoother at idle, and at lower RPMs.

I'd think $56 would be money better spent on one of those than $256 spent on a CAI. Not as purty though.
