Recently picked up a 2020 GLC43 Coupe and loving it, sporty enough for everyday drive but the OPF/GPF is really killing the exhaust note, especially in S+ when I'm trying to get those burbles

It sounds like the engine is being choked and everything's too muffled for my taste

I've been hunting for some pre-owned aftermarket exhausts, specifically looking to mod the mid pipe and resonator (so yeah, everything after the cat). Since GLC AMG isn't really that common in the aftermarket, I've only found sellers with 2017 and 2023 model parts.

Here's what I know:
  • All GLC43s from 2017-2023 share the same chassis codes (X253 for SUV, C253 for Coupe)
  • Fi-Exhaust lists the same system as compatible for both X253/C253 from 2017-2020 (though their site seems outdated as it doesn't list anything post-2020)
  • They all run the same engine (M276 V6 3.0T BiTurbo)
Has anyone done a similar swap? Will exhausts from 2017 or 2023 models fit my 2020 coupe?
