Voodoo Design Porsche 991 GT3 Center Muffler Bypass

The Voodoo Design Porsche 991 GT3 Center Muffler Bypass eliminates the restrictive factory center section to unlock the raw, mechanical sound your flat-six was built to make. Crafted from TIG-welded, Type 304 stainless steel, it sharpens the car’s character—deep and aggressive under throttle, yet composed when cruising thanks to full retention of the OEM side mufflers and factory valve system.

Built 100% in-house in the USA, this system is CAD-designed and fixture-welded for a precise, bolt-on fit. Back-purged TIG welds ensure maximum strength and durability, while the laser-cut hex mesh brace with the Voodoo Design logo adds both structural support and signature detail.

Finish options include:

• Raw Brushed Stainless: A clean, motorsport-inspired finish with visible grain and exposed welds that show the craftsmanship.
• Cerakote Black, Bronze, or Silver: Advanced thermal coatings that reduce heat, resist corrosion, and maintain a premium look.
