707… We knew from the beginning that we’d have some fun working with the mighty Challenger Hellcat, but we just didn’t know how much… First impressions: wow. Power is definitely an understatement for this one. The face-melting acceleration of the Hellcat will change your definition of “fast car.”
We began prototyping the Roar Racing Super GT, a non-valved, no-nonsense, purists performance exhaust system. The full system features a dual 3″ X-Pipe which leads into a pair of Roar Racing mufflers specifically engineered for HEMI engines in order to provide maximum performance gains. The exhaust exits the rear of the car through our double-walled LeMans style quad tips. All of this hand built from T-304 grade polished stainless steel. Picture below:
The result of all of this is a tremendous improvement in power over the Hellcats original, restrictive exhaust system, as well an extremely aggressive sound that one of our Instagram followers described as “when your speakers can’t even create the actual sound because too much muscle.”
Numbers wise, this Hellcat will now be tearing up the asphalt with a newly found 29 horsepower and 35 ft/lbs of torque, at the wheels! Enough reading for now though, turn your speakers up and enjoy the video!
