Has any one used a pipe expander to take out the crimp in the factory down pipe?

You could try having a exh. shop bend you a 120 degree bend on a peice of pipe 1/2" larger then the stock pipe,(you'll loose about 1/2" in the bend) and cut and weld the new peice in to replace the kink.

allready bought the header (its in the mail) i can get the expander for 10-20 bucks so it seams like a good idea.

Go flex you jeep and see where the front drive shaft winds up befor you fit a custom down pipe. You can beat it in with a hammer if it hits for clearance. Somtimes you flex both sides at once like on a whoop de doo so consider where it will be when it goes straight up also.

how are you gonna get the pipe expander in far enough to open up the pipe?

My stroker with headers now has a crimped spot. It is due to the ujoint hitting the pipe under full flex.

my d-shaft still hits my down pipe at full tilt so i don't want to spend a lot of money to get a new one when it's only going to get dented again.
The crimp is on three sides so if i could get it round and let the d-shaft reclearance it. It would still have better flow than it does now.
Im only running a bb and 30'' tires when i lift it enough that it wont ever hit again ill get a different (better) down pipe.

my muffler man couldnt custom bend a 2.5 front pipe that would clear the axle at full travel. he actually admitted it "whooped" him!
I ended up with a new, stock 2.25 front pipe, with the lovely dent.
he said the header's collector dumped out at the wrong angle to fit a 2.5 front pipe.
the nearby fuel line locations are to blame for the exhaust routing as well.
its a really crowded spot on a 4wd jeep, with exhaust, diff, driveshaft, and fuel lines all crammed in there.

I looked at JCwhitney.com and I don't see a down pipe listed. What is the item #? Does it have the sensor mount?
