AIRTEC MOTORSPORT Sport Exhaust De-Cat Downpipe
AIRTEC Motorsport De-Cat Downpipe for BMW B58 Engine.
By removing the original restrictive catalytic converter located within the factory OEM downpipe, back pressure is hugely reduced, which in return means faster response, increased power and a more aggressive exhaust note.
