Just put on my Buschur 3" turbo back w/ magnaflow muffler yesterday. First off, great fit, great finish, not too quiet, not too loud, and lots of power. However, this morning I got a check engine light (CEL). I realize that this may be because the 2nd o2 sensor is not recognizing a catalytic converter, but I didn't think that people were having problems with that. Earlier in the day i was playing with my AFC and went out of range with it for a moment(which is another possible cause of the CEL), but I didn't get the CEL until about an hour later. Anybody had this problem yet? Anybody know a fix or know if its ok to run with the CEL if its because there is no cat?

THANKS!

 

I've been running with my CEL on for about 3,000 miles cause of my gutted cat, and it doesn't seem to hurt anything. Only really bad thing is that big ***, bright orange light in the dash at night!

 

take the dash out and pull out the light that goes into the CEL one. THE BEST CEL FIX. But i rather have my car running good with a 3" cat
