i had mine fixed by RPM, although you can go to most any shop, muffler shop, and ask someone to re-weld your collector, yes remember to strip the coating off of where it is you are about to weld but as far as getting a new header, for some that isnt the best choice of REPAIR...I reccommen trying to have it fixed, its very easy and definately possible...If youwant i will upload pics of my blow KB before and after for proof of completion/stability.
