GrimmSpeed doesn't want you to have any exhaust leaks, so they designed these exhaust adapters to use between your exhaust system and downpipe. If you have an aftermarket 3 inch downpipe and stock style 2.5 inch exhaust or an aftermarket 3 inch cat-back and stock downpipe, using the correct GrimmSpeed adapter will provide a solid mounting solution for the gasket on each side, eliminating the risk of leaks. The GrimmSpeed Exhaust Adapter even features a clean tapered transition for optimum flow (most alternatives have a abrupt step that can cause turbulence and limit power). Installation hardware and instructions are included to provide a simple worry free installation process.

Key Features:
  • Virtually indestructible.
  • Smooth taper does not obstruct dlow.
  • Leak free precision fit.
  • Simple installation.
