Did you keep your stock exhaust? Is it hard to go back to stock from the Eisenmann sport? It would seem that welding the eom rear section back together would have very little tolerance for tip adjustment.

Has anyone done this yet successfully?

Is your sport exhaust too quiet? Do you wish it was a little louder?
