Challenger SRT8 Dyno Test

It seems MagnaFlow Performance Exhaust has been having a bit of dyno fun with the new Dodge Challenger SRT8

The SRT8's already got a 6.1L Hemi V8 that's good for 425 hp and 420 lb-ft of torque but why stop there? Since more is always better, as this video shows, why not see what a dual inlet/outlet 18in. resonator, dual 11in. rear Mufflers, a 3in. system and dual rear exit without tips will do for you?

Apparently, a fair amount! 12 horsepower and 18 lb-ft, to be exact, which makes this particular Challenger 437 horses strong, with 438 lbs of grunt to back it up. Nice!
