Our dealership just installed a corsca exhaust system on a 09 challenger. HOLLY S*&T it was spendy, but VERY much worth the cash. Had the correct looking split tips, all stainless, and improoved low end torque, and throttle responce. THis is a stick car, with the super track pack 3:73 gears. Awsome car, I grabbed 2nd gear with minimal effort lost traction. Fun car, I wish I had one now. The fun factor is amazing. 5.7 6 speed will run for sure!
