Doesn't the panhard bar interfere with the tail pipes?
I used a diagonal locator bar on my Duster with ladder bar and coil overs with a stock gas tank and had the 3.0 inch tail pipes ran like side pipes under the rockers on the body and then tuck under the rear end housing with the muffs mounted behind the rear end and the rear bumper up between the 1/4 panel and rear sub frames
The side pipes hid the ladder bars completely also
