WOW, Almost 106dB's!?! Geez. Well that is for the Single Tip, I imagine the Dual Tip exhaust will still be right around those numbers (probably less though I would think since it has a smaller cross section on the dual than on the single IIRC). So how much of a difference would the silencer make on that thing? Would it bring it down below 96dB's?

How does this compare to the Apex'i N1 Dual? What is the dB rating on the N1 Dual?

I have never seen or heard of those other exhaust systems (prolly cause they are JDM).  Do you have any pictures of those other ones?
