Decat
The Drakonic high-flow decat-a-C downpipe for your BMW M3 gives your vehicle superior performance.
Our downpipe is made of SS304 stainless steel, hand-welded using TIG welding. This downpipe improves engine life, significantly reduces exhaust temperatures, and makes exhaust gas evacuation faster and more effective. Optionally, we offer HJS high-performance thermal insulation for a better finish and more efficient environmental protection.
In addition to all these benefits, we offer new and improved diameters for our downpipes. These diameters are larger than the stock ones, thereby reducing the pressure drop at the turbo outlet.
Our products are model-specific and come with adapters for perfect fitment to the original exhaust system. The product includes mounting holes for sensor installation, if necessary.
All these benefits translate into increased power, torque, and a better, deeper, and sportier engine sound. This is an essential component for Stage 2, Stage 3, or Stage 4 tuning.
This product eliminates the catalytic converter and the particulate filter (if equipped), so use on public roads is not recommended.
