The B-King's underseat exhaust utilizes a large-capacity catalyzer just aft of the O2 sensor, with the SET exhaust valve behind the catalyzer. The collector-box underseat muffler does a good job of suppressing noise, but smaller volume than the 'Busa's twin conventional mufflers means less power as well.
