finally did it , thanks to a few friends to hook me up with the exhaust, diffuser, install of the diffuser and exhaust , i netted just under 700 dollars for the whole thing including installation

as for the sound i dont know how to upload a video clip lol, it does have minimal drone that doesnt bother me at all

question though is between gears when im driving with my sprint booster and sport mode on, it makes a "blurp" sound, does anyone know what that is?
I just got mine done last weekend. There is barely any drone but its sounds pretty good. Are your valves open?

As for the blurps, it caused by a ignition cut on upshifting (this is a common method of managing WOT shifting in manual/DCT transmissions). When the ignition is cut for a split second, unburnt fuel enters the exhaust and ignites there when ignition is switched on again, causing a explosion
