I have a 2020 C43 AMG Coupe and wanted a little bit of modifications to the handling of the car.

I’m currently considering:
- Hardrace (Front Strut Brace & Middle Lower Brace)
- KCDesign (any of their braces)
- Ultra Racing (any of their braces)

For those who have installed any of these:
Was it worth the money?

Did you notice a real difference in handling or steering feel?

Any downsides or increase in NVH?

Which brand would you recommend?

Would love to hear your experiences. Thanks!

Currently fully stock exhaust, no M Performance Exhaust. I don’t want to do a tune, downpipe, or anything that could cause a CEL.

Mainly just want a deeper louder OEM+ sound with minimal/no drone since it’s my daily. I’m confused between resonator delete or muffler delete

Also, if I do resonator delete, should I replace it with straight pipe or a Y-pipe/merge pipe setup?
I’ve heard Y-pipe sounds smoother and less raspy but not sure.

Any recommendations from people who’ve tried these setups on an N55 E82?

Thanks in advance!

Anyone with a W205 C43 AMG PE setup running a resonator delete replaced with another H-pipe? Basically double H-pipe setup since there is already one right after the resonator from factory.

I was originally considering an X-pipe, but a lot of clips sound raspier and seem to lose some of the loud aggressive AMG upshift bark that the PE exhaust already has. Trying to keep the deep AMG tone while avoiding going fully straight pipe.

Anyone got clips or experience with it?

I have a 2020 C43 Coupe with the factory AMG Performance Exhaust (valved mufflers) and I’m trying to make it a bit louder/deeper without going catless, tuning, or doing downpipes since I don’t want CEL issues.

I’m planning to keep the stock mufflers because the valve control is honestly really good already, so I’m mainly looking at modifying the middle resonator section only.

I was thinking about replacing the stock resonator with a performance resonator or maybe an X-pipe setup, but I’m a little confused on what works best since the setup is 2 inlet / 2 outlet.

For those who have done it:
- What resonator setup sounded best?
- Any recommendations for deeper tone without too much rasp/drone?
- Any idea what the inlet size would be? (is it 2.5”, 2.75”, or 3”)

Also I’m in California, so a lot of companies won’t even ship exhaust parts here because of Prop 65/CARB regulations which makes it annoying to buy parts.

Would appreciate any recommendations or sound clips from similar setups. Thanks!
