Will this downpipe fit my W205 C63?
Yes, this downpipe is engineered to fit all Mercedes-Benz C63 and C63 S AMG (W205) models from 2015–2021 in sedan, coupe, and cabriolet variants with the M177 engine.

Do I need to remove my catalytic converter?
You have the choice: select the high-flow catalytic version for improved emissions compliance, or the catless race version for maximum flow and sound. Both bolt on directly.

Can I install this myself?
The downpipe is a direct bolt-on design, but professional installation is recommended to ensure proper alignment, sealing, and leak-free operation. Contact Project Styling on 07540331557 or sales@projectstyling.co.uk to arrange fitting in Southend-on-Sea.

What power gains can I expect?
On a stock tune, expect 20–30 HP gains. Significantly greater gains are achievable when paired with ECU remapping or Stage 1/2 tuning software.
