Vacuum line location for rear muffler?

Hey!!

Where is the vacuum lines for these cars? I just got my car dynoed and it's low on boost. The tuner said it could vacuum lines. Anyone have any photos or know where exactly the lines are?

Thanks

Hey buddy, they come down right where the factory exhaust valve would be. There's a heat shield, I know you changed your exhaust reach up there you may feel them just laying on there.

Here are some crude pics, not an M5 but will give you the idea.

Hey all,

I am fully straight piped and I have fabspeed muffler delete and resonator delete and I have never had issues for months and now the car drives slower than stock and I was pushing 700hp with race fuel... I am not sure what they did with the vacuum lines since I have no more valves. Is there another area the vacuum line can be or is this the only exhaust one that they are referring to? Please help...
