This listing covers model years 1975, 1976, 1977, and 1978 Mark IV and Mark V’s.
Photo depicts the dual cat-back system for a 1978 Mark V stock with converters on both manifolds. This photo was taken long ago and shows the resonator inlet pipe as a separate pc. We now have patterns for the LS/RS resonators and that pipe is now an integral part of the resonators.
- Dual cat-back exhaust system consists of the H pipe (2 pc.), LS/RS mufflers, LS/RS connector pipes, and LS/RS resonators with tailpipe. Please be certain to specify if your Mark is stock with 1 or 2 cats during the check our process.
