B58 Gen 3 Catless Downpipe

Unleash the full potential of your turbocharged engine with the MBS GEN 3 Catless Downpipe. Engineered for maximum performance and designed for precision fitment, this high-flow downpipe eliminates the restrictive factory catalytic converter to deliver increased horsepower, improved throttle response, and a more aggressive exhaust note.

Constructed from premium T304 stainless steel, the MBS GEN 3 Downpipe is built to withstand extreme temperatures and harsh driving conditions. Smooth mandrel bends and a carefully designed flow path reduce turbo lag and promote faster spool-up, making it the ideal upgrade for enthusiasts seeking more power and efficiency.

Key Features:

• Direct bolt-on fitment for GEN 3 platforms

• Catless design for maximum exhaust flow and performance

• T304 stainless steel construction for durability and corrosion resistance

• CNC-machined flanges for a precise, leak-free seal

• Improved turbo response and enhanced exhaust tone
