We're waiting for it to reach production. The STR's exhaust is purposely clogged-up by Jaguar to be quiet. So you're gunna weld in a pair of Magnaflow hi-flo cats, 2 1/2" pipe, followed by a Magnaflow x-pipe (2 1/2"), 2 1/2" pipe to a pair of 12" Dynomax glass packed tube pre-mufflers (behave as resonators), 2 1/2" pipe over the axle to a pair of Dynomax Super Turbos. This full exhaust mod should yield approx. 30 hp and torque not failing to mention an authoritive but not overbearing exhaust note. Next call EuroToys and order a low temperature thermostat and a 2.5/3.0 supercharger pulley. The pulley alone yields approx. 30 hp and torque. Viola! Approx 75 hp and torque. If you think she's kind of quick and grunty now....

Along with a low temp thermo, the uncorked exhaust lowers block temps too= more power due to less heat soak thus causing the ECU not pull back timing but add more ignition lead with more boost from the 2.5/3.0 pulley= more power. The ECU adapts wonderfully to the new found gulps of air and accomodates accordingly with more fuel and spark lead. More power moves the 3900 lb. mass more efficiently= less fuel consumption. You'll def. notice the increase in power and torque. Though I'll hopefully prove with a dyno...I'm guessing with Mafioso's air intake tube; my STR will be belting out 475 hp @ 500 lb/ft torque. BMW's, Audi's, MB, and American muscle? They'd never know what hit em. Yes, these mods are "relatively" inexpensive.
