Guys

Just threw on a garage-R decat pipe, with built in CEL fix (I guess this is just the welded flange on the side the sensor bolts up to).

Problem is I still get an engine check light. Shouldnt this just be: unbolt the cat and remove the sensor, switch in the new pipe and re attach the sensor. Enjoy. (no gaskets to change or anything?)

Can someone help please?

 

my invdia 70mm with cel fix works like a charm but some people still get it. they do this and it should work.

Thanks man, will try that. Just need to see if i can get tose here

 

just add a couple spark plug defoulers to the bung, then bolt the sensor back in...theyre like a dollar at auto part stores

 

just so you know, the '06 and above are more sensitive to readings, even with a CEL fix they are known to throw the CEL, even if you add another defouler. It may work for a few weeks or months but you will eventually get the code back. There is a defouler out there the has a filter built into it but it's like $50 or more, you can try puttting some SOS pad fibers into your defouler, that will act as a filter and may stop you from throwing a code. good luck
