Milltek Valved Rear Silencer - Porsche 992.1 GT3 - SSXPO171

Milltek Rear Silencer for Porsche 992.1 GT3 - direct factory fitment using OEM tailpipes, no modification required. This cat-back component replaces the original rear silencer while retaining your existing tailpipe setup, delivering engineered sound character and aesthetic refinement.

Hand-finished T304L stainless steel construction ensures durability in all driving conditions.

Each silencer is mandrel-bent and CNC-formed for precise fitment and optimal flow.

Fitment options:

• Resonated Rear Silencer - street-legal, refined tone character
• Non-Resonated Rear Silencer - track-focused, full-throttle sound
