i recently put on my magnaflow 2in1 headers/cat that i got from procivic. supposed to be oem/legal but i got a check engine light now. had o2 censors checked and theyre good so i did some research and found that i prob need the check engine light blocker thing for o2 censor befor i put another dollar into this i need confirmation or feedback. is anyone familiar with this situation?????????????

Might you be talking about an o2 sensor defouler? I've heard of them, but I don't know much about them. I just checked a generic link with some info though:

hmm if its a legitimate header cat combo then you shouldn't need a O2 simulator you could have just bought a megan header for $100 bucks then used the simulator . but anyway robear racing sells the megan angled O2 simulator thats what i used because i ran into clearance issues with my alternater here is the link
