Middle muffler delete EU with OPF?

urke85 · 01-16-2019, 02:47 PM

Hello

Did anyone try to delete middle muffler? Is any drone in the car, is much more nosier exhaust?

I m waiting for Remus exhaust, but is EU and i think it will be to quiet and i was thinking to take middle muffler off if it helps to a better sound.

I know if we take OPF filter down that we have a lot of exhaust noise, but than we have to flash the car and we lose waranty, thats why i am looking for different solutions.

EU spec OPF'd M4 comp with several parts of OE exhaust gutted by PCW.

Sounds lame with flaps closed but with valves open sounds better....gives an indication of how OPF'd M2C might sound with similar mods

This company is modifying the oem exhaust. This version is the loudest they have for now. But there is another one coming!

Milltek do several variants, OPF back with race or EC middle silencer.

Or full OPF delete or just axle back only.

I was trying to get informations from PCW but nothing.
Maybe someone knows what they do with V2 mode (mid resonator mod)
They just maybe take out insulation or some other modifications...?
