Downpipe for Mercedes E53 AMG / E450 W213 A238 C238 (3.0 M256) reduces backpressure, which helps the turbo spool faster and improve throttle response. AXI Performances offering two options for the Mercedes E53 AMG / E450 downpipe - catted downpipe (with a 200 Cells Sports Catalytic Converter) and catless downpipe (decat).

  • Reduced Turbo Lag: AXI Downpipe reduces backpressure, which can help the turbo spool faster and improve throttle response.
  • Increased Horsepower and Torque: By improving exhaust flow, AXI Downpipe can increase engine output, especially when combined with an ECU remap or tune.
  • Improved Exhaust Sound: Upgrading the Downpipe results in a deeper, more aggressive exhaust sound, as the gases flow more freely.
  • Made from Sandblasted Stainless Steel (T304) for durability and heat resistance, 3 years warranty.
  • 100% OEM fit, easy to replace factory part (for models with or without OPF/ GPF);
  • Catalytic Converter Heat Shield;

Frequently asked questions (FAQ)

Which is Better: Catted or Catless Downpipe for Mercedes E53 AMG?

Catted Mercedes E53 Downpipe: Pros and Cons
Catted (short for "catalytic") downpipes contain a high-flow catalytic converter that allows for better exhaust flow than the factory unit while still reducing harmful emissions.
Pros:
- Street-legal (in many areas): High-flow catted downpipes are more likely to pass emissions inspections and avoid triggering a check engine light (CEL), especially when paired with a tune.
- Reduced odor: Catted downpipes minimize the raw fuel smell often associated with catless setups.
- Lower risk of fines or inspection failure: Important in countries with strict emissions laws.

Cons:
- Slightly less power than catless: Though they offer a good performance bump, catted downpipes don't flow quite as freely as catless versions.
- Higher cost: The inclusion of a quality catalytic converter increases the price compared to catless alternatives.

Catless Mercedes E53 AMG Downpipe: Pros and Cons
Catless downpipes remove the catalytic converter entirely, offering the most direct path for exhaust gases to exit the turbo.

Pros:
- Maximum performance gains: Less restriction means more horsepower, better turbo spool, and increased throttle response.
- Aggressive sound: Catless systems are typically louder and more aggressive, which some enthusiasts prefer.

Cons:
- Illegal in many jurisdictions: Removing the catalytic converter is a violation of emissions regulations in most areas.
- Check engine light: Without tuning, the lack of a catalytic converter almost always triggers a CEL.
- Strong exhaust smell: Especially noticeable in garages or at idle.

The “better” choice depends on your priorities:
Daily Driver / Street Legal Build
→ Catted Downpipe
A high-flow catted downpipe balances performance, legality, and comfort. Ideal for drivers who want a boost without legal headaches or excessive noise.
Track Car / Maximum Performance Build
→ Catless Downpipe
For those chasing every bit of horsepower and not concerned with emissions compliance or daily drivability, a catless downpipe is the more aggressive option.
