Ben zo vrij geweest om een mailtje te sturen naar Eisenmann zelf :ok: Wat ik eruit opmaak is dat de demper sowieso zal passen, mits lichte aanpassingen aan de steunpunten? Mark, wat het overige gedeelte betreft, vinden we wel een oplossing. Suggesties zijn steeds welkom :smart: Dit was hun antwoord: Dear Mr. De Schutter, thanks very much for your e-mail. If you have a RACE muffler for the Z3 2.8l, you can install it to both engines. There is no difference at the back box itself. But the brackets and fastners are different! If you are trying to install a muffler designed to fit to the Single Vanos model to a Double Vanos model or vice a versa, you have to modify the fastners and brackets. For your car, we do only offer the back box. We do not have a complete cat back system. With the best regards Sven Johann (Sales director) En dit was mijn vraag... I am interested in installing an EISENMANN SS exhaust on my BMW Z3 2.8, dating from 02/99. I have one question though. My Z3 is a DOUBLE VANOS model. Does this need a different exhaust to when it would be a Single Vanos model? The plan is to install a complete line starting from the catalyser. Thank you very much for this information. Kind regards, Maikel De Schutter
