2019 Dodge Challenger R/T (Plus)
About This Build
The 5.7 HEMI needed to wake up. Started with headers and a tune which transformed the car. The stock exhaust was way too quiet - Corsa Sport catback gives it the muscle car rumble it deserved without being obnoxious. Cold air intake and 85mm throttle body helped it breathe better up top. Dynod at 425hp to the wheels. Not bad for a 5.7!
