i'm not saying i would buy this RennTech smart, but i WAS curious as to what the 'kit' was that they installed. as i said, i have yet to hear back from our smart center.
besides, my original plan was to install a dual center-exit exhaust if for nothing else, LOOKS!
but thanks guys for all the info on the RennTech equipment. not my cup of tea, but i'm sure it will work for someone........
