I have the greddy evo gt with ART pipes, not Supercharged, and it definitely drones. Which is unfortunate because it sounds amazing above 3k and WOT. I can’t wait to hear it fly by me or what people say when i take it to the track. There is a narrow rev range where you can eliminate the majority of the drone, or just stay above 3k
, and depends on what highway speed you go because i think 55-65 is drone. May be high too, I don’t remember.
Sometimes i wonder if my ART pipes are real because it has so much drone and people claim ART pipes reduce drone compared to hfc or test pipes, meaning their heads probably explode on a daily basis.
The idle and natural backfires are nice
