I don't have any pictures handy, but I've had both TTI 1 3/4" and 2" primary on my car. The 2" hung a little lower as it had a 3 1/2" collector vs a 3", but both were tucked up nicely. I prefer the 1 3/4" as it makes life a little easier to work on. These were on a race car that had a 18" collector and a 6" muffler attached, didn't have a full exhaust system.
