Just an update to this ebay downpipe. I still have it on my car and just had my yearly inspection, first one after installing it. I passed the emissions with it. However it was very close call, but still a pass. CO emissions were 1.5% and 2.0% is maximum allowed. HC (CH) 30 ppm, 100 ppm is max allowed. The day was hot and I made sure engine was as hot as possible also.
