INSTALL YOUR AFTERMARKET CATBACK THE RIGHT WAY!

• Flanged for OEM Donut Gasket
   
• Machined lip centers 2-Bolt Gasket
   
• CNC Machined Steel Construction
  (Zinc coated for durability)

• Simple bolt on installation
  (Supplied with quality hardware)

• Includes GrimmSpeed 3" 2x Thick Gasket
  (For a PERFECT seal!)

CNC machined from mild steel and zinc coated for durability and longevity, this thing will outlast your car. Don't waste your time trying to get your OEM downpipe to seal without a donut gasket. In a short amount of time, they rust and corrode and will prevent you from ever getting a good seal with a typical flat gasket. Re-use your stock donut gasket along with a GrimmSpeed 2x Thick 3" Gasket (included) for a perfect seal on the first try! 

A final solution to pesky problems, it's what you can expect from GrimmSpeed.

Fitment Note: Adapter is only intended to be used for connecting an OEM Downpipe to an aftermarket Catback. We produce a different adapter for the opposite purpose.
