Installation and care

  • BORLA® system is True Dual
  • Muffler contains an internal H-Pipe
  • Oversize box shipping rates apply to this system
  • Borla states that this T-304 true dual system weighs less and flows more than the factory single system.
  • 140638BC, 141027BC, 141028BC: Using BORLA® Stainless Steel Polish p# 21499 is NOT recommended with these black chrome tips.
  • 140638BC, 141027BC, 141028BC: We suggest cleaning the tips with hot water and a microfiber cloth.

Use Borla’s instructions for the selected part number before fitting.
