Just ordered a rear bumper cover! SWEET! My baby needs some TLC on the cosmetic end...
Sorry I can't help with the codes, but definetely go with a header, there is a catalytic converter in the stock header to help with cold start emissions but it really isn't neccessary. Just like Black I went with the OBX 4-1, its a fair price and gives noticable gains and I have herd that when paired with a Racing Beat cat back it's very nice, both in performance and sound (not ricey at all!). That would be my suggestion. Keep us posted![]()
Codes are pretty easy to erase as long as you are sure the problem is taken care of. I have the P0421 code stating "warm up catalyst efficiency below threshold bank 1". It is one of the sensors (bank 1) that I transferred from the stock mani to the OBX header. Not an issue that effects the driveability. I was able to borrow the code reader from an O'Rielly's and just erase the code after I fixed it.
And then u saw my build... lolNice to see some other CO folks on here! My "build" isn't like some of these other guys who gut everything and throw a V6 under the hood. I just have a decent list of moderate improvements. However, us Colorado peeps should keep in touch. Thanks for subbing, and I'll take a look at your threads tomorrow when I'm not on my cell phone!
