Exhaust System Upgrade Options Available for Turbo I4 AMG Engine Yet?

really need to know what codes his car is throwing. For all we know, it could not even be exhaust or valve related.

That didn't work. After recalibration it still threw check engine light

Update: drove 20 miles or so after recalibration and the check engine light went off.

What is your scanner showing before when you had CEL? and now that it is clear, that means the code(s) moved out of permanent into temp then cleared. Usually getting a new code takes around 3 drive cycles and same for clearing. Just carry your scanner I use a small bluetooth OBD2 since codes pop up all the time on these cars. Mine goes from rich to lean to stuck O2 sensor, etc. Some of them have been coded out on my tune but there's still a few that pop up. The only ones you have to worry about are the valve exhaust related ones that limp mode your car...sounds like you don't have that anymore otherwise you would have noticed. Sometimes a blown fuse for the valve is the deeper gremlin in the panel behind your driver's seat. But yeah if you don't already get a scanner off Amazon super convenient to clear things. And I think on another thread lots of suggestions and opinions but definitely get a sports cat from whoever (Aerie, GRP, Mach5, etc.) or cat delete, and then get the Mach5 straight pipe...it's crazy how good it sounds.
