Muffler setup after T9.645 delete

[cropchopper1022]

Just deleted a T9.645 and running Ekotuning. Wondering if the muffler needs any changes or if it can stay as is. Anyone run into issues?

You should be fine leaving the muffler as is with the Ekotune coz feel it shouldn't be a problem given that it's calibrated to handle stock exhaust setups and in a case where you're not seeing any performance dips or odd backpressure signs, there's no real need to mess with it unless you're chasing a different sound.
