Hello dear Saab drivers! I don’t know if my concern has been dealt with before. I put it in the room with this: On my 2,3-suger the exhaust was due according to time, and both pots. Since the parts in the contract workshop had to be ordered first and cost a small fortune, I looked around for an alternative. I assume that Saab does not produce the silencers himself and therefore it is unnecessary to pay for the name. As an example of price, the rear silencer costs approx. 340,– in the Saab workshop alone and in the Flenner catalogue (named “original” 154,–. In a fast workshop it is required for part 190,–, for a total of 465,– for both silencers including work and two years warranty I was able to pick up my vehicle already two hours later (without lengthy pre-order). The parts are now manufactured Walker, the mechanic assured me that Saab will also receive them from there. Now I am but not really satisfied with the result, the sound sounds like something leaking, although twice was checked and no leak was found. Now I am unsure: Does Saab build its silencers for example and foreign parts are really only “cheap” copies? Does anyone know more about it? Do I have to try to have a quiet vehicle next time, after all, the expensive contract workshop or are there better suppliers? Another technical question on the side: What is the respective function of the two silencers and which one is responsible for the noise? Thank you for your opinions and advice! Alex
