The final obstacle was fabricating the over-axle pipes. There isn't much space between the muffler outlet and the rearend, so Eggen used a 90-degree bend to turn the pipe upward sharply. From there, it hooks up with another 90-degree bend, followed by a straight pipe that runs over the axle. Next, another 90-degree bend routes the exhaust downward. Before mocking up the pipes, the rearend was jacked all the way up to ensure adequate clearance during suspension compression.
