hey i have an audi q7 s line 2011 and one of my buddies opened his exhaust valves permanently and i was thinking of doing the same thing but I just couldnt find the vaccum line and was wondering if any one could help me

 

Exhaust valve? I'm not sure what you're talking about. If the exhaust valves I'm thinking about are permanently open, the engine will not run and has suffered head, valve, and piston damage. So obviously you may be referring to something in the exhaust system, no?
