560SEC performance exhaust

Last year I had the exhaust replaced on my 560SEL.   At the time the exhaust was rubbing on the drive shaft and had a few holes.   I had a custom stainless system built that I am really happy with.    This year I saved up to do the same thing on the 560SEC.   While the SEC’s exhaust wasn’t rubbing, it was starting to get a few rust holes.  It was also sometimes scraping on the ground even after replacing some hangers.  In addition, somebody had previously removed the back box and welded in an oval tip I didn’t think suited the car.   It’s been bugging me since I bought the car back in 2018.

As the SEC is the 10:1 compression ECE model, it has a different exhaust system as standard than my 560SEL.    The exhaust manifolds are two piece on each bank and go through longer headers. This is illustrated in the picture above that can be compared to picture in the 560SEL article.    This is often referred to as the ‘tri-y’ system.    Based on this, I was looking for a 560SEC performance exhaust.

As can be seen in the picture below, my new exhaust retains this feature. It is now in stainless steel 2″ pipe. I’ve saved the original pieces to remain with the car too.

I had actually bought some AMG style tips, but due to the curvature required in the exhaust, I had these tips made up.   I think its a pretty good compromise to make sure the exhaust doesn’t impact any curbs.  My 560SEC performance exhaust sounds great and it should last a long time

    Saw your post while continuing the search for a replacement middle “kidney” sound suppressor system in my 1988 560SEC, & am interested…

    I have a gr8 exhaust mechanic, but he’s not good with substituting from vintage parts…If I can get the parts, however, and show his a pic, he could pull it off…

    Can you tell me what you actually ordered to replace the old system?…I can then work with Alex to get it into place…

    Thanks much…

    Hi Rob,
    I took the car to a custom exhaust shop here in Sydney and they took care of everything for me. So I didn’t have to order any specific parts.

  • […] outside temperature display, purchased, refinished and fitted the AMG Aero I wheels and had a new stainless steel exhaust system installed.  The A/C was also recharged.  There is a minor leak from the compressor.  […]
