Hey all! Recently got my catless downpipe installed and jb4 going running map 1and 2 (depending on driving) and upon start up the backfire is super loud and healthy but after coming to a complete stop (at a stoplight or stop sign the burbles get really quiet, raspy and metallic sounding I was wondering if anyone has encountered this issue and know a fix!
