agreed, use a programmer and fine tune your engine as a package. You may still get some small popping if you chop the throttle. good luck and enjoy

what do you do with the wiring that plugs into the stock exhaust after you put on a aftermarket one do you just eliminate the wiring?

I do not have the 09 manual in front of me, but I would think that tucking the wires back is ok, since it tells the ecu what the exhaust valve position is. Program your fuel map to compensate to fine tune it.
