Ive listened to several different exhausts and love the way the Powersticks sound. I heard tons of clips of the Sticks but none on the 4.7 Tundra. Anyone out there got them on their 4.7 that can post a sound clip? Also, let me know what setup you have, single or duals. I have an aftermarket muffler on now and it sounds very good when on the gas but has some drone to it while cruising. I talked to Eric at Classic Chambered and he suggested either one 2.5 inch stick or dual 2 1/4 inchers. Like to keep the cost down but like to hear suggestions on both. Thanks.
