I will be interested in your results. BTW, FVD also makes their exhaust with 200 cell HJS cats so they are an option for anyone wanting the stage 2 GIAC tune. I hope to get dyno results on my FVD boltons with IPD plenum and no tuning to see how the combination of passive mods affects performance. Then I will see what the difference is with both FVD piggyback and then Cobb Stage 2. That is the plan or so I have been told.
