After my OEM header in my GS-R cracked (A-Pipe), I replaced it with a DC Sports ceramic coated header that I bought used. I've been using it for about 6 months, but now this one has cracked too (also A-Pipe).

Do you guys think it is worth having it welded, or will it just crack again fairly soon? I can't decide if I should have it repaired or just buy a new/used header that is higher quality.

 

Sounds like you aren't using a flex pipe? Install one, reweld the header, enjoy.
