Exhaust and down pipes help
So I just recently ordered catless downpipes but then it occurred to me that I might need a different exhaust. I’m not too familiar with how this all works, it’s my first time doing this so I’d appreciate the help, thank you!

You can keep the stock exhaust but you'll need a tune.

Encore is correct. If you have the catless downpipes the rest of your exhaust will be fine however a tune will be needed to code out the O2 sensors.

I have catless downpipes and a stage 2 on my 2016 C63S, runs great no issues.
