SSC keeps the catalytic converters in the car. They don’t sound bad with minimal mufflers and cats, pulling one cat out for ST* is a big leap in noise, basically removing the cats or the mufflers doubles the noise, removing both quadruples it. Probably won’t blow sound at most scca events with headers + minimal/no mufflers and oe midpipe (between 95-100db depending on the site/region) but I know I don’t like cars that loud.

Hell I’d keep the stock mufflers if my jack could fit under it, but fitting the jack and dropping 15# is worth it most of the time.
