After market parts on here are rare, and that exhaust system even more so, try speaking to @cgrautomotive
In the 3 years I’ve owed my 250 I’ve only ever seen one Ackra come up for sale on the 2nd hand market and it was silly money. They’re like unicorn sh*t and ridiculously expensive.
Can not see the point in forking out that much money on an exhaust for a road car in the 1st place. loosing weight on a race car makes sense, as it could be the difference between 1st and 2nd place
