Custom Catless Manifold + BMS Downpipe Fix Install

Hi All,

I had these custom stainless manifolds made. I installed them last night with the down pipe fix. Car feels quicker and I noticed an insane increase in mpg. I'm in Canada so I was at 12.5l /100km. It dropped all the way down to 7.9l /100km at one point. .25% increase in fuel economy. Anyways, I ran a baseline dyno before I put them on last night with my stock exhaust system. Only addition is a euro air box. I am going to go back and dyno in a week or so.

Only problem, is I got a CEL today. I put the DP fix setting on 5. Not sure how I need to adjust it and what it will take to clear it but I don't know which exact code it is. Anyways. Here are the pipes I installed.

I'll keep everyone updated on the dyno plus which setting clears my CEL. if anyone has any suggestions let me know.
