2010 Challenger 5.7L R/T with Corsa Sport Cat-Back exhaust, K&N Cold Air Kit & Hypertech Power/premium tune - smooths low end, obvious low-end torque drive-ability. No appreciable change in mileage either way - 19 or so mixed driving, 22-23.5 all highway. Excellent. Seems a lot for a few ounces of aluminum but remember the engineering costs. Maybe not the fastest car on the street but WAY more competitive with the additive improvements. Ordered a second one for my other 2010 R/T MOPAR-10.
