Installation Notes

Verify the vehicle year, make, model, and exhaust configuration before installation. Walker 42283 uses a 2-bolt loose flange with spherical flare at the inlet and a 2-bolt loose flange at the outlet, so flange alignment should be checked during mock-up before final tightening. Confirm the listed position, including Front, Front Forward, or Crossover To Pipe, to match the vehicle’s exhaust layout. Part number 42283 is a specific-fit replacement and should be matched to the exact application shown in the fitment data.
