17 When it comes to the over-the-axle section, it is best to get a second guy (Brandon Silva in our case) to help angle the pipes around for the best fitment. It's best to do this with the suspension at ride height so if you have the car on jack stands, make sure they are under the axle. This is also where you want to determine tip placement. We are sending it right out the back so having the pipe run straight is best for us. If you want your tips to exit out the side, then design that accordingly by articulating the sections so they point to the rear quarters.
