ZC33S - X-Force Suzuki K14C BOOSTERJET Downpipe Kit

Hey everyone,

Considering the X-Force Suzuki K14C BOOSTERJET Downpipe Kit for my 2020 Suzuki Swift Sport. Does anyone know if it needs a tune? How is the sound on a stock exhaust? Mainly looking at it for performance upgrades, but don't want to run a tune due to legality (can do it if really needed).

Thank you :)
