Product Details

The APR CBK0003 cat-back exhaust system is engineered specifically for the Audi S3 Sedan (8V chassis) to deliver enhanced exhaust flow, aggressive styling, and superior build quality. This performance exhaust system is constructed from premium T304 stainless steel throughout, ensuring excellent corrosion resistance and long-lasting durability in all weather conditions.

Key Features:

  • Direct bolt-on installation with no modifications required
  • T304 stainless steel construction for maximum durability and corrosion resistance
  • Larger diameter piping compared to stock for improved exhaust flow
  • Precision-engineered cast 3-inch to quad 2.5-inch splitter for smooth flow transition
  • Polished 4-inch slash-cut quad exhaust tips (removable)
  • Argon-back-purged TIG welding throughout for superior weld quality
  • Rugged, precision-fit mounting brackets for secure installation
  • No weight increase over factory exhaust system

This cat-back system replaces the factory exhaust from the catalytic converter back, providing an aggressive exhaust note while maintaining excellent build quality and fitment. The ultra-smooth cast splitter ensures optimal exhaust flow distribution to all four outlets, while the removable polished tips allow for customization options.
