im thinking about getting ether the megan s pipe or the invidia s pipe or some sort and then straight piping it all the way back from there to my greddy exhaust.
my question is would i get a CEL, i assume i would so if i went to a muffler to get the straight pipe put in would they be able to get the secondary O2 sensor in the pipe to eliminate the CEL or what are my options

i believe only a aftermarket header could cause CEL. Spipe and exhaust should not cause Cel.

I just wasn't sure where the secondary O2 sensor is because I thought it was in the CAT and a straight pipe would eliminate all those CATS and resonators

You have 2 cats, one in the header and one in the mid pipe. As long as you have a cat on your header you're fine.

Well that's pretty awesome now just to find a muffler shop that came custom bend all the piping and not charge a ton

I regret emptying out my cat by the header. It's full 2.5" straight pipe and smells like gas 24/7 and now I wanna get oem headers with cat and go back to Tsudo N1 catback exhaust and have a clean non smelling sound. If you have a cat by the headers then you'll be fine.
