all you need to do is undo screw the bolt which holds the battery rail fella, then you can lift the rail and slide the maxogen trumpet in place
it literally take 5mins to fit the maxogen.
taken the acoustic valve out will take a little longer though lol, although you dont need to do it straight away, you can run the maxogen with the acoustic valve still in place.
one tip i would give you is dont connect any cold air feed directly to the maxogen, instead have the feed supply air to the 'airspace' behind the headlight where the maxogen trumpet draws the air in
ja.jack: i rekon like all induction kits, the claimed bhp gains air a tad optimistic lol, compared to the viper i had, i found the maxogen to be quieter, and a lot smoother! i felt i got a few flat spots with the viper pre 5k but the maxogen helps the motor to pull smoothly across the whole range
