Im want to build my own 5in exhaust from the muffler back. Might want to run duals.. I'm looking just for the bends that go over the axle.. I know flow pro has 45* and 90* 5in tubing on there website but no prices. There only 12in long so I don't know how many pieces I would need I have 5in exhaust pipe laying around I'm just wondering if these angles would be enough to run over the axle? Thanks!
