Muffler delete question

[nc1500]

Does anyone know of any muffler chain stores who carry pipe big enough to straight pipe my stock 7.3 exhaust? So far everyone carries 3" OD (max). Online kits are $60 plus...

Might try your local IH dealer or one of the big rig shops??

some of the larger chrome shops sell exhaust parts
