Hello together … Since unfortunately no one came up with a company that produces a duplex system (two rear silencers), I took it into my own hands. By the way: My Saab car dealership “refused” to do something in this direction … Fortunately I know someone who knows a small, fine fine tuning forge. So there … and they built me a special stainless steel system and hung it under it … There is a sonorous greeting in front of him PS: The perspective deceives e in little … the two tailpipes look straight out and are equally far away from the respective rear apron … the right section in the spoiler lip has to be repaired again a little bit
