I just ordered all the exhaust parts I needed. I went with the 3" Dynomax Bullet Race mufflers that are 4" Round and the body is 12" long.
It will go from headers to the Tweek Chamber I made then snaked through the ladder bar cross member to the tail pipe section that goes over the axle to ust past the rear of the tire it will then turn past the frame and then hit the mufflers in that open section under the rear quarter then it will dump in the corner on both sides just above the rear valance where it meets the end of the rear quarter so it is not seen. when walking around the car.
