Ill make this quick and as short as possible. I have a 2007 Dodge Charger R/T and i want to do a exhaust upgrade. I saw that CJR Performance installed a hellcat exhaust onto a 2006 R/T and i would like to go that direction with mine. They used Hellcat headers and the full catback exhaust system. Wondering if anyone has any knowledge on if the headers would just bolt onto my 5.7? or what/how much modifications would need to be done to the headers and the rest of the exhaust? any help would be greatly appreciated or if you could push me towards the right path on who can help. I would have CJR Performance do it for me but they want $2500 to do it and im currently in college and would much rather do this over the winter when the vehicle is being kept in the garage.
