TTI exhaust muffler option

Well I drove around and around and I tried to get past it but the Walker super turbos are just to loud for me. Im now an old fart that has spent over 23 years around jet engines and other loud hotrods and I just cant take the drone and loudnes at part throttle and idle. I have a drag car and I can handle that but my street car needs a bit more civility. I prefer a quiet sleeper as opposed to a car that wakes up the neighbors. I know there are people that think there to quiet but I now have to search out a longer case muffler. So now I have two sets of mufflers to sell.
