^thank you! your post and the post you quoted is quality information that I look forward to. Not just a one line response that doesn't answer anything. I have the exact feelings about an exhaust that you described. I do not want to make it a race truck. I do not want to worry about any warranty issues. I do not want to worry about passing inspection. I just want an improved sound and look. A cat-back exhaust is for me and I think I'm going with Silverline! You don't happen to know the cost of a 304 system, do ya?
