you need bung spacers installed to move your O2 sensor out of the main stream of exhaust flow, so it does not read high enough to set off the sensor alarm.

 

i know this might sound like iam a retart but can you just tell me where the bung spacers go and where do i purchase them just elaberate more i would really appreciate it

You can buy them pre-made from ConceptZ Performance: http://www.conceptzperformance.com/C...370.246.42.239, GruppeS or on eBay. They'll cost you about $20 a pair and they're simple to install (at the rear or the muffler end of the test pipes). See picture below.
