We are extremely proud to introduce our Catless Divorced Downpipe for Subarus. It's safe to say, the years our engineering department spent on this downpipe have paid off. A GrimmSpeed™ Catless Divorced Downpipe is one of the first modifications that should be done on your car. The OEM downpipe contains two very restrictive catalytic converters, killing the power potential of your car (not to mention the oem blocked wastegate port).

  • Proudly made in the USA - Design, Materials and Fabrication
  • Innovative 3-D Contour Flange 
  • FARO™ Arm Designed - Leading edge of new product design hardware
  • O2 Bungs for factory sensor and aftermarket wideband AFR
  • Divorced Wastegate for Optimal flow
  • High-flow, 300 cell, metallic substrate catalytic converter
  • GrimmSpeed Gaskets Included - A $40 Value!
