Exhaust is a disappointment compared to my X3MC
I am really surprised that the exhaust is so quiet on my 24 G87. I just heard my wife leave in the 22 x3mc and it has me thinking time for a upgrade to Papa Smurf.
How do you open the valves on the stock exhaust?
Seems that most like the full Valvetronic Designs - Valved Sport Exhaust System, anything else I should look at?
Thanks
