Repair it and it will collapse again real soon. Replace it with any SS aftermarket header and avoid the Ti stuff that does not hold up! :thumbsup:

I just repaired a crinked 450 pipe recently. It was mashed up pretty bad and I was able to "re-expand" it by capping the ends and applying compressed air inside (it only needed about 5 - 10 psi) while heating it slowly with an acetylene torch. It didn't come out perfect but certainly very servicable. Yours doesn't sound half as bad. If you have access to a gas welder you might give it a try.
