Got to love their effort at trying to say it has a positive effect on performance 
I also had to giggle at the better dispersion comment....WOOHOO! just what the world has been needing, that's got to allow for an astronomical decrease on pollution levels.....right? LOL.

Worst marketing drivel of all time:


"Furthermore, the exhaust gases emanating from the tailpipe will be uniformly dispersed into the atmosphere"


Their claim about improving response could actually be true on certain N/A engines with certain exhaust systems by providing more backpressure (read: obstruction), but will be met with a reduction in flow at high rpm

granted for low end response but unlikely to be worth the trade off at the higher end.
