Stage 3 Minus downpipe

[Tanner77]

Hey guys, my fiesta is my everyday driver but I pushing it to its limits because I know my car can handle it. But the main reason I came here was to ask if I could run stage 3 on the Cobb AP without the downpipe. I have everything else but the downpipe and I don't really want/need the downpipe unless it's essentially for running the stage 3 Cobb tune on the AP. Looking forward to hearing back from you guys, thanks.

I would not personally recommend running a tune that is designed for a TBE without the downpipe.
With that being said, a feasible solution that is cheaper would be to get the Stratified flash tune; they will gear it towards your specific modifications and there is no cookie-cutter "stage" sequence.
