went in to a local shop and paid for airbags for the rear suspension .the mechanic came and took me back to the truck to show me my banks exhaust would not allow installation of the pass.side bag.I loosened the hanger bolts and clamps and tried to pry the exh.pipe over to the diff. enuf to fit the bag and hardware but no luck today.tomorrow we remove the pipe ,install the bag after removing a corner of metal from its anchoring hardware stuff the pipe back in.........hope fully.I will be putting a OEM tailpipe back in as the exhaust has no real perfomance gains on this model truck ,the dpf/DOC are the same dia. as the banks exh.
