We have just receieved our 40 foot container of Invidia Exhausts. And in the shipment is the Down Pipe for the Liberty BL5s Manual

The Down Pipe is one of the best on market for Flow, but does require a Steering Knuckle from an STI Impreza to clear .
These can be purchased seperately for $99 or $60 with down Pipe
