Hi i got a 97 Integra GSR and i just bought a test pipe for it and wanted to know what was the best method to keep the check eng. light form coming on and messing with my Air./ fuel its hard to find a 02 Sim because the gov. put a stop to them Aug. but i see them still out there and i looked at a post and he said just put the o2 senser in the outlet hole the test pipe has and it wont mess with the honda ecu??? What best thanks
