Hmmmm drone.....Did dual exahaust on two of my last cars and the freeway drone was irritating as hell. On my Lexus I ripped out the back seats and the trunk liner and did a full layer of Dynamat, really helped to knock the sound level down. Lack of intake options for the 45 makes me crazy but The Beast, Chedman, and a few others have had good luck with the JWT Pop Charger set-up. A couple of guys on the Org. also built intakes off the lower scoop that direct the air up to the intake. I think fabbing something up isn't too hard, it may not look pretty but if it gets the air where it needs to be....The JWT was reported by multiple sources to add 1 MPG and a few horses, again it supposedly plays very well with the exhaust. Using the stock airbox is mainly a Dremmel cut out but I like the way it maintains the ram air and keeps some of he cold air flow somewhat closed off.
Too bad Gordon and the Invidia crew don't have a marketing plan considering the cash they have spent on R&D, manufacturing and the associated overhead. From a baseline marketing effort it should be you and anybody else who steps up as initial buyers. They should be encouraged to post results off a list that describes factors potential buyers need/want to know good or bad. Easy to do and it builds on itself. Marketing and import are both a big part of my background, it makes me crazy to see an unpatented potentially great product ramp up so slowly.......
