Hi guys, I've had my check engine light go on a few weeks ago and the code mentioned that the O2 sensors were running in limp mode causing the car to run rich. After taking her into the shop they informed me they found a crack in my headers before sensor 1 and before the cats bank 2. I've got a set of GMS Ceramic Coated Headers (Can be seen here: http://www.greenmotorsport.us/servlet/the-241/GMS-987-Cayman-fdsh-Boxster-fdsh-S-Sport/Detail ) The headers and cats are 1 piece and purchased 2 years ago. What do you guys suggest I do? 1. Have GMS replace the headers under some sort of warranty? 2. Wrap the headers? 3. Have the ceramic coating grinded off the whole headers/cats, have the crack tig welded and put them back on? 4. Have the ceramic coating only grinded off where the crack is, have the crack tig welded, and put the headers back on? 5. Have the ceramic coating grinded off the whole headers, have the crack tig welded, have the headers wrapped, and then put them back on? 6. Have the ceramic coating grinded off the headers, have the crack tig welded and put them back on without any heat protection? 7. Have the ceramic coated grinded, have the cats cut off and eliminated, tig weld the crack and add an extension to the FVD exhaust. 8. Any other ideas? Keep in mind this is my daily driver. Thank you
