Deep Loudmouth II™ Growl. The deep muscle car sound and big HP gains of the Loudmouth™ are now available in a more refined version for your C6 Corvette. If you love that big bad sound, but want something a little quieter than the original Loudmouth, you'll love the tone of the Loudmouth II's polished stainless bullet-style resonators.
Big HP and TQ Gains. With a free-flowing, straight-through design, this catback has been dyno-proven to add up to 12HP. Engineered and designed to exceed OEM standards, this exhaust offers a superior fit right out of the box for long-term durability and an easy bolt-on installation.
