Here's some pictures of the first fit of an SLS stainless exhaust on a 230sl.
The car is almost finished a major restoration, I can't vouch for the fit of the rear silencer as I built the car to fit it! Both rear silencer hangers were welded on to suit the fit if the rear silencer.
It all needed small tweaks but nothing major, the system.comes with 2 stubs that bolt to the manifold, the twins pipes then slide over them and are clamped to the stubs. Biggest issue I had there was the small turn in these pipes sent the system too far towards the centre of the car, I had to heat each bend, bending one slightly forwards and one slightly backwards so the pipes would line up in the recess in the floor. Everything else lined up good, apart from cutting small pieces from.the ends of some of the pipes all was good.
Just bear in mind that car has had major reconstruction so some lining issues may be with the car and others with the exhaust!
