MSL PERFORMANCE 3.5" DECAT DOWNPIPE & MID PIPE A45 W176 / CLA45 C117 / GLA45 X156

MSL Performance 3.5″ Decat Downpipe & Mid Pipe for A45 / CLA45 / GLA45 AMG

Unleash the True Voice and Performance of Your M133 Engine.

The 2.0-litre M133 engine in your A45, CLA45, or GLA45 is a high-strung masterpiece, but it’s held back by a restrictive factory exhaust system. The standard catalytic converter and downpipe are designed for emissions and comfort, not for maximum performance. To unlock the full potential of your AMG, you need to free up the exhaust flow.

Our 3.5-inch Decat Downpipe and Mid Pipe is the ultimate solution. By removing the restrictive catalyst and increasing the pipe diameter, we drastically reduce back-pressure, allowing the turbocharger to spool faster and operate more efficiently. The result is a monumental improvement in performance, throttle response, and sound.

This isn’t just a pipe; it’s a precision-engineered performance component. Manufactured from high-grade materials, it is 100% TIG welded and back-purged for incredible strength and durability, ensuring it can handle the immense heat and stress of a tuned engine. Designed as a direct, 100% bolt-on part, it requires no modifications for installation, making it the perfect upgrade for any enthusiast.

Key Features & Benefits:

• Significant Performance Gains: This is the key to unlocking Stage 2 power. When paired with our custom ECU remap, this downpipe allows for a huge increase in horsepower and torque.
• Sharper Throttle Response: With the turbo spooling faster and more freely, you’ll experience a dramatic improvement in engine response and a reduction in turbo lag.
• Aggressive Exhaust Note: Transform the sound of your AMG. This downpipe unleashes a deeper, more aggressive, and purposeful exhaust note that is truly addictive, without being overly obnoxious.
• Improved Thermal Efficiency: By evacuating exhaust gasses more quickly, this downpipe helps to reduce under-bonnet temperatures and mitigate heat soak, leading to more consistent performance.
