I have a 2019 challenger scatpack widebody. Thinking of buying jba shorty headers to install. What do you guys think? Any thoughts of the exhaust sound after installing? Any hp and torque gains?
Good advise.The 6.4 (392) comes with shorty headers, I think you will find very little gain over the factory headers, the 5.7 factory may be a different story but not by a lot from what I have seen posted on this site.
