4.69 out of 5 stars 122 Customer Reviews

These 70 Series Big Block II mufflers are designed around a large case for maximum volume and efficiency. They're 2 in. narrower than the original Big Block muffler, making them easier to install into tight areas. Other features include a mild, mellow exhaust tone and a resonant tuning chamber for reduced interior sound levels.
