Hi Dan I think you'll notice a sweeter sound with siamese )( over X pipe. Also, a tad of power... but you'll need a dyno to tell probably Carbon Dynamic airboxes do a funky swirl thingy... I put them on stephens car last week, but didn't take pics I'm afraid. Easy to fit. Basically, just remove the whole std air box, and fit these in their place. Kit comes with everything needed although the flexi pipe is crap, need rubberised stuff really, and you have to be creative with how the intake matches to the bonnet inlet. Local cost in Oz is ~$490 each AUD. You need 2. Image Unavailable, Please Login
If you could please provide me with direction to the link, I would be happy to review it. Heck, for the $200, I'd be happy to get measurable improvement! Thanks!
Its not just measurable, it's audible and tangible. And it doesn't even cost any $.. if you service your car you'll no doubt be charged for new air filters at some stage... the BMC are for LIFE, and they only need cleaning once in a blue moon. Over a typical 5 year ownership, you'll save money by having BMC.
Phil: I've considered going to a conical shaped filter for the obvious reasons of benefit. Nice to know someone's got a package out there. 490 AUS is not bad at all. Further, I'm absolutely convinced that the siamese pipes will have a sweeter sound than the x-pipe. Why do you think I want a mk3? --Dan

How was cats removed? I am pretty much decided against test pipes due to emissions rules here (having to swap out, etc) but may go with a hyperflow type of system --Dan
Right, i remember that. I meant what kind of gains did you see? You know how obtuse I can be No need to post the dyno just curious on basic numbers --Dan
dan I honestly don't know off the top of my head. It can't have been huge otherwise I'd remember! EDIT: It was 15-20kw at the rear wheels, I think.
yes, 18kw at wheels by my reckoning looking at the graph from recent testing. I reckon thats huge... ~35-40BHP at flywheel.
I'd say that's a substantial jump. If you assume that filters and x-pipe / siamese put yo uat 540 crank, this jumps it up to 575-580! Sign me up! Although diminishing returns for power are soon becoming evident. --Dan
