- Dual exhaust system consists of the LS/RS exhaust pipes, LS/RS mufflers, and LS/RS tailpipes.
- 1964 & 1965 models have options regarding the tailpipes. In the check out process you will be asked to report your desired exit; out the back (toward the bumper) or exit out behind the rear wheels (designed to fit up to the split chrome tips that we do not offer).
- For MY’s 1970-74; this system does not include the chrome tips. We suggest you contact Ames Performance Engineering.
