Wow, sounds like a damn good salesman to me!

*wink*
No but really hard to say if its faster i'm a skepic and would have to drive to have proof... But if its got the borla exhaust and K&N drop in filter, both those parts can come from the Nissan Motorsports catalog and so maybe theres some other internals in there from the same catalog?
The Nissan dealership i work at is starting a new ploy on getting the younger generations to adapt to nissans, we are removing the stock hubcaps and steely's on base GXE sentras and putting american racing ones on (same 15" size) and tinting windows and putting a system in em... In my opion its funny stuff!
Although we have done some "factory mods" that the coustormers orded from us and we put on... The first is a Black 2003 350z Track edition that we put leather in and a upgraded system like the touring models come with. The other was a 2002 Spec-V that we put Stillen CAI, Stillen Axel back exhaust, Stillen rotors, Stillen Pads, and Stillen steel braided lines on.
