I have a new ACR and highly considering the full Belanger set up including their headers, cats, and exhaust plus the Mopar PCM (installed by my Viper tech who has done many of them). For those of you who HAVE this complete set up installed on your Gen 4, are there any negative sides that you have personally experienced such as CEL, rough running, or anything else I might need to know. Im aware its expensive and loud and thats fine but dont want issues down the road. Whats your personal results, good or bad? Thanks in advance.
