I wanted to upgrade my impact x plenum. I dont like the cylinder external plenum. So between the mk2 plenum and Michael plenum, which is better? I've seen pic of Michael plenum. It looks like its offset and not center. And bottom of the tube extended out too far imo which make it look funny or weird. What are you guys opinion. Get the mk2 or Michael? The thing is Michael site gives no info about it and no way to purchase it. Do we have to contact him on forum or what? Dont even know his forum name.
