First of all a thank you to H.P.! Yeah, it was the cable! Great how you know yourself!
But I would have another question: My V8 sounds a bit too good with the standard exhaust system. Who knows if there is a fine exhaust baser in the Nuremberg area, which can help me to a double pipe exhaust system. I don't want to have a tubular oversized part out the back, rather two subtle (likely oval) tubes on the left and right at the rear. No roaring in the interior but only a beautiful, deep V8-browsing...!
Of course, I would also take other cost-effective rear silencers from various tuning companies. Just a tip! If necessary, the pot will remain on the left side (if double pipe is too expensive). Greetings, and always good ride! Stephan
