Great buy, worth every penny!

Easy installation with clear instructions, comes with dyno before and after car with the same engine, looks and sounds amazing and most importantly I can feel the difference in performance! Got rid of the sluggish start, slightly easier in the mountains. 10/10 worth the investment.
