exhaust 450 sl (1973)
 

The exhaust has been completely replaced and the car sounds like a small truck. I cannot find any leaks. I removed the vaccum
advance hose and the car runs much quieter. This can't be the solution,maybe the distributor is bad . Does anyone have any suggestions.HELP!!!!!!!!!!!!!

Did you use OEM (Eberspacher) exhaust components or go with aftermarket replacements? Ansa and Borla exhaust components are considerably louder than their OEM counterparts.
