Today I got my 1.6 turbo Kona a custom exhaust deleted catalytic converter, deleted resonator, magnaflow mufflers. Did this to go with the DTE piggyback tune, cold air intake, snow performance water methanol injection already installed. I just like going fast.
Nice, can you post some pictures, and do't forget to switch out the resonance tube too. It gets rid of the "stumble" in normal mode when starting to go in 1st gear.

Just remember to use high hold hairspray all over the tube and the inside boot to seal the turbo boot on all removed connections. I have T-clamps coming Friday to help seal better too.
