The 1970 Chevy Chevelle offered several different exhaust system options, depending on the specific trim level and engine configuration. Here are a few examples:
- Base Models: The base models of the 1970 Chevy Chevelle typically came equipped with a single exhaust system. It consisted of a cast iron exhaust manifold on each side, which funneled the exhaust gases into a single exhaust pipe. The exhaust pipe would then lead to a muffler and tailpipe at the rear of the vehicle.
- SS Models: The Super Sport (SS) versions of the 1970 Chevelle often had a dual exhaust setup. It featured a pair of cast iron exhaust manifolds, one for each side of the engine, which directed the exhaust gases into separate exhaust pipes. These pipes would then connect to a dual exhaust system consisting of two mufflers and two tailpipes, typically with chrome tips.
- Optional Performance Exhaust: Chevrolet offered an optional performance exhaust system known as the “Chambered Exhaust” or “Chambered Power Pak” for the 1970 Chevelle SS models. This system included special mufflers with chambers that helped create a more aggressive and distinctive exhaust note.
It’s important to note that aftermarket exhaust systems are also available for the 1970 Chevy Chevelle, which offer different options for sound, performance, and customization. These aftermarket systems can range from simple bolt-on replacements to complete custom setups.
When considering modifications to the exhaust system, it’s advisable to consult with experts or professionals who specialize in automotive exhaust systems to ensure compatibility and proper installation.
