Hi MBWORLD!
Looking to see if anyone has any recent experience acquiring downpipes for their GLC43. The only notable one I found was from Logos Engineering Motorworks. Only issue with these are they are catted, while on 250 cells -- I'm looking for catless. Redstar has some but anything associated with DHL shipping gives me trauma!

I have heard many people say "search for C43 downpipes they probably fit" -- I will buy C43 downpipes IF AND ONLY IF they fit -- but I don't want to take a shot in the dark assuming a good C43 downpipe will fit my 2021 GLC43. I know both the GLC43 and C43 share the M276 motor -- but i want to be sure about fitment!

Appreciate all and any advice! Also willing to buy any if someone has for sale

I have a 2021 GLC 43 as well and have been interested in downpipes. What is the difference between catted vs catless except noise? Does this mod void warranty?

to my understanding -- the only difference is with catted you would maybe receive 10% less of the gains you would with catless. can't speak on warranty, as if you are concerned with warranty you should just leave the vehicle stock in totality....BUT -- warranty aside-- if you're getting downpipes for more power, you may as well get catless. the bright side to catted are you MIGHT**** find a company that has a product that doesn't trigger a CEL -- LOGOS ENGINEERING MOTORWORKS has one like that I believe.
