If you want noise, go buy some PVC pipe from Bunnings or wherever with the twin 90MM ends on it, put 2 pods on it and it might give you some extra noise.
I don't know much about making more induction noise, i never really got into that whole thing. I had a pod set up on my old VP, but i did a proper one that looked bog stock from the engine bay. Left the factory airbox in, took a fresh 90mm holesaw, cut through the bottom of the airbox and through the steel into the wheel arch (tyre removed of course just in case), took some 90mm PVC piping, slid it into the hole with an angle piece on it so the pod cleared the tyre, used plumbers waterproof silicone to seal everything up, bracketed and bolted the PVC pipe into place so it didn't move, added a second small piece of 90mm PVC pipe to the angled section so it pointed directy at one of the factory left and right side holes in my VP Senator front bar, and Sikaflexed a K&N pod onto the end.
The reason for the extra piece of PVC pipe slotted into the end of the angled piece, was so i could pull the pipe out and wash and oil up the pod filter as they do need weekly cleaning when in a front bar set up.
Worked bloody well. Didn't cost much either. I'll try and dig up some photos.
