Good evening. Was already in the Mercedes Forum .. there they could not help me so right. Thought you could do it… Ride an old Limo W126 MB V8. Would like to get out a real sound… Don’t have this big-volume engine in it for nothing… Do you have ideas how to get the louder still(GRUSELIGGGER?? Endpot is already empty… isn’t enough yet… What do you think you can do, that it sounds like an amishlitte zb Corvette??? Thank you already in advance.–
