Tylers turbo vert sounds good above 4,500 RPM. he has a custom 3" exhaust. Low in the rev range though, it sounds like a Powerstroke diesel. I have the exhaust cut off right after the cat in my '89, and that is way loud. It sounds good at idle, but it sounds like a damn cannon going off when you get on the gas, LOL. And at certain RPM's it vibrates the whole interior. You can seriously hear that exhaust from over a half mile away. It can also resonate really bad sometimes. I often find myself with a headache when ever I drive that car for more than 15 minutes, haha.
