Cool to see there is an all Whipple web site! I've had mine on my '03 Cobra since Jan '09. It's currently putting down 570 rwhp, and 540 tq... and it's still got the stock cats (for now!). I'm running a 2.3L with a 3.0 blower pulley, GT fuel pumps, 60lb injectors, SCT MAF, JLT RAI, and all the other normal upgrades. A 2 cat H-pipe will be going on next, along with a new tune, for the push to 600 rwhp. I got 98% of all my parts from Lethal Performace. Thanks for all the great prices, Jared!
