I have the FS CoolFlo with heatshield, Borla 2.5 inch exhaust and some other small things not worth mentioning. Last week, I drove a friend's stock SVT and he drove my SVT and his comments were mine seemed a lot quicker and he loved the sound as well...is it worth the $650 or so for the two, I think so...I think throtle response is a lot better among other things. JRSC vs. Vortec...if you don't mind the work involved including drilling into the engine amongst other things, Vortec...the JRSC is simpler to install but you're not going to be blown away with the performance...it is also quite a bit cheaper...if you have the @$2,800 I'd do it...Another thought is do simple bolt ons and work a little on the suspension...even though the SVTF's suspension is pretty darn good.
