Mate, I'd get my ears checked if I were you. I din't notice any reasonable difference to exhaust note, intake whistle or 'push back' into the seat. Your original post stated you don't care how much more power you get, you just want more induction sound. If this is the case, I doubt you will achieve it with these components alone. I'm not so sure I agree with your statement of ' I can only feel a little difference down low'. If you refer back to my dyno chart you can see that up until approx 3800rpm there is pretty much nothing in it. Only after about 4000rpm there is a rise in power. I wouldn't exactly class this as down low. However, each car will have it's own characteristics and as I don't know what sort of ambient temps or fuel you're using your comments could be very well founded. As for your exhaust note. Huh?? How would your exhaust sound any different if you didn't do anything to it? :o
