350hp stock, Magnaflow exhaust with Steeda CAI 404hp. </P>


**Quote from site**</P>


Another bone-stock '03 Cobra was there, and posted numbers of Power 350.6 and Torque 358.8. Interestingly enough, Bassani x and cats added 20.2 hp and 9 to torque for him. </P>


I'd say Magnaflow won..by A LOT!</P>

<FONT size=2>Now Matt's new Cobra was no slouch, it slapped down 389 hp and 372 ft lbs of torque on it's first run. The second run he ran 386 hp and 369 ft lbs of torque. This is pretty much standard for a stock 2003 Cobra with a Flowmaster catback system &amp; CAI.</FONT></P>
