I'm looking at upgrading my '98 Expedition. The exhaust manifolds are leaking agian so I'm looking at replacing them with a set of Supermaxx headers with hi-flow cats, a magnaflow muffler with custom split out the back exhaust, and an Edge programmer. Is this a reasonible combination for a vehicle with 182,000 miles? The body is real good with only the bottom of the doors needing some attention, so I'm not afraid to put the money into it.

 

sounds good to me... might i recommend taking a look at the Xcal series or programmers
