I just installed jba longtube headers to my 2013 charger srt8. I am currently having issues when I start my car it takes a while to turn on also my car does not run good like before I can’t even press the gas all the way it won’t even go fast. It just stays there rpms are not working good what could be my issue? I installed my o2 connectors they all installed but I’m not sure what’s the issue. If any body could help thank you so much.
