Hello. Incredible but true ! In June advertising brochure of the ATU there is this offer -> rear silencer costs one € per PS 🙂 I sent an e-mail to my ATU branch, of course an e-mail has come back that this offer does not apply to the Smart, because with Kat etc…. blablabla I complained at the ATU headquarters in Weiden and see there got the commitment for an exhaust for my Smart. Of course a Eberspächer with KAT and ABE 🙂 I attached my bill to you and a picture of the montage. Perhaps this offer still applies to you good luck with greetings Thomas Edit by Derk: The picture pendants were removed at the request of the author.
