cat replacement resonators i found a sweet deal on ebay from obx racing sports. LT headers, cat replacement resonators, and y pipe. with all provisions for my 99 ss and it's all stainless!
Heres my delema... are those resonators gonna set an SES light? if so, can i have it turned off to smog it? and if i can... will it stay off? thanks for any help guys.

yes, they cat replacements(even just the LTs) will throw a code. Yes you can have them tuned out. When you say 'smog it' are you talking CA smog test? Because the LTs won't pass inspection, you gotta get shorty headers
