The custom-designed inner baffles are tuned for optimum airflow and that awesome muscle car rumble! Remember, “Sweet Thunder Mufflers” are available in aluminum steel or “304 Stainless Steel.” Your total satisfaction guaranteed. The “Custom” versions are the same mufflers, but with a more mellow sound.
