FS: Audi RS4 (B7) Milltek Exhaust, Resonated with Lamborghini-style Vacuum-Bypasses

[smash]

These valves that we added work off-of the factory "S-button" ECU-signals for the rear vacuum-solenoid that controls the valves to deepen the exhaust note. These are not the same as the pointless, tip-located valves that Milltek/Stratmosphere offers. We added our own, for a much better sound and loud/quiet user-controllability with the car's factory system!

The setup we've created here definitely produces the best possible blend between noise, performance, and controllability. You can press "S" to go back to quiet-mode, or press it again to go back to the more aggressive, exotic sound. It's not as loud as a Milltek Unresonated-kit for this car, more of like a "Resonated+" sound... yet normal Resonated with the valves closed.

Also allows more flow and more power!

Asking $1300 (as-is) for the exhaust. WILL ACCEPT BEST OFFER!! Includes all of the clamps and some heat-wrapping we did (just-in-case). Very nice setup, I will negotiate shipping with you, if necessary.
