I just finished ( DIY…..no credible muffler shops who could do this job anywhere near me) replacing my worn out OEM exhaust system (1970 280 SL auto) with an aftermarket steel system sourced from Buds Benz. This is a tedious job as you need a hoist for starters and need to be able to take out OEM a exhaust as one piece ( original system was welded end to end). If your OEM system is already out, you are half ay there!
The aftermarket BUDS system came as:
(1) new manifold to resonator down pipes with integral crossover.
(2) new resonator…..must fit up to AND weld to down pipes. Install downpipes and tack weld resonator after carefully lining up….the fitment in this step is very critical . Remove from car and circumferential weld down pipes to resonator.
(3) resonator to muffler "S" pipes x 2. These are bolt up both ends using muffler clamps….makes install and fitment much easier.
(4) muffler and twin tail pipes…..bolt up with muffler clamps
(5) BUDS supplied all new hangers, rubber donuts, 50mm clamps, new exhaust bolts and copper alloy nuts and exhaust manifold gaskets (2)….suggest you order4 of these gaskets as you need to install / remove down pipes several times.
While a tedious job, ALL THE AFTERMARKET PIECES FIT WELL TOGETHER.
