Deep Loudmouth II™ Growl. The incredibly popular deep note of the original Loudmouth™ is now available with less volume and the same power punch of the original for your 09+ LS3 Corvette. If you love the big, bad muscle car sound, but want something a little quieter than the original Loudmouth™, then the Loudmouth II™'s bullet-style resonators deliver the exhaust note you're looking for.
