I have a new exhaust system installed in my 2013 c63 , but i like to know what are this buttons on the back locate it in the black box or electronic module. Also i felt the car is not as loud i expected.

Those are for adjusting the sensitivity on the solenoids. I'm guessing the valves are closed, there's a remote that comes with the kit to open them up, assuming they're wired. Or you can zip tie them open.

They are wired but since the system didn't come with a manual a was curious about it . thanks for the help.

thats weird. When I ordered mine it came with wiring schematic. I believe you can also download one on the A.P. web site. Had mine installed at the mech. shop. They had no prob. with the one that came with it.

Not a fan of the key FOB tho. Gonna get my audio guy to install led on/off button and get rid of the fobs all together.

I bought the full exhaust headers to mufflers. CRAZY loud! I'll post a dyno video when I'm back from overseas.
