My buddy just bought a '99 prelude...decided that the Greddy Sp2 set up was the way to go but had someone install it...Got to excided and couldn't wait for the weekend so that I could help he with it...Anyways when he started the car up after the shop installed it he noticed his "Check enigne" light was on...the only answer I could give him was that they might have knocked the O2 sensor and loosened it?...I don't drive a prelude just wondering if anyone else with any cat-back has had this problem?..anyones two cents would be helpfull...Thanks

 

yeah he probably did something to the o2 sensor on the cat... check what code it is though.

edit**did he reset the ecu after putting the exhaust on?
