Performance Exhaust Hangers
I was hoping someone may have the part #'s for the performance exhaust hangers. Specifically, the two middle-rear ones that attach each mid-pipe and the upper rear ones for the mufflers. I cannot for the life of me figure it out on parts websites as their descriptions are the least descriptive descriptions I have ever seen.
I retrofitted the performance exhaust and currently have it jerry-rigged using the non-perf. hangers and it works. But I'd like to complete the process and I think it may reduce some vibration issues I'm having when I put catless DP's on.
thanks!

U78 is the benz option code for the valved performance exhaust, jsyk. Try these: A2054902940 right hanger / A2054902840 left hanger, these are for the rear end of the mid pipes. EPC doesn't specify the performance code U78 for these, only 5U1 (aluminum rear axle carrier) . So not too sure if they are correct. The hardware is N000000007953 says you need 4 of them with Code U78. And that's searching EPC using the VIN of a C43 with U78 factory installed.

Thanks for your response. I was wondering if you had any more info on the hangers for the mufflers? The non-perf has 2, whereas the performance has 4. I think they may be the same. The EPC I looked at I don't believe is correct. It identifies part # A 20 549 024 40 and A 20 549 026 40 but I believe those are for C300 and E43. I have an issue now where the exhaust tips are banging against the exhaust housing at the very rear in 3rd+ gears at around 3k rpm and on some shifts at partial throttle.
Thanks

However, I haven't found part numbers for the mid pipe hangers.
