agreed 100% no performance gains ,i dont plan on doing it either, but a job like that deserves to be seen by all who own 690s, lolTake it from someone with dual exhausts ('05 625 SMC), stick with one if you can. I guess to some it may look cool but there's no perfomance advantage and it's just more weight. On another note, thank God we in the states don't have to have those big ugly license plates. I mean, that guy goes to all that work and money to put those duals on and then he's gotta put that speed limit sign on the back. That thing is hideous! :headshake
thats bad ass, but......
:laughingsHey now he can melt BOTH turn signals!!! :laughingr:rofl:
