Picked up my SRT6 yesterday after installation of several NeedsWings modifications: Overdrive Crank Pulley Kit; Tweaked Lower Y Pipe; Tweaked Stock Manifolds w/Crossovers; Exhaust Manifolds; Waldig Supercooler; ECU tune. Rob at NeedsWings is a pleasure to work with and was very helpful as we selected the upgrades. Installation was by Benz & Beemers in New Baltimore, MI, who also did a fantastic job. The exterior of the vehicle is still 100% stock.
