2021 Kia Forte GT. Black.
I'm very happy with the custom exhaust I am running. Any T shaped muffler will fit the axle back portion, and imo the mid pipe is great... Just remove the resonator.I don't think an affordable header would be feasible. I think if you get the cat-back Evilla exhaust you'd be happy with the sound! I'm enjoying the DSG "farts" with the Evilla cat-back exhaust and I have the DCT.
The downpipe is the only expensive exhaust add on that I would think I will eventual need to do. The Evilla exhaust is nice though. I just got my Evilla stage 1 suspension kit in the mail today, so I can finally feel safe throwing the Eibach's on the car.
