So I bought this ragged out rusted 7.3 yesterday I shouldn't have but I drove 2.5 hrs and payed for fuel allready and had the trailer there. It's a 1999.5 f250 lifted on 20s with 05 clip ext cab 6 speed 4x4. It's got some electrical gremlins I have to figure out but the engine seems to run decent shifts good just needs lots of tlc. Well it had a new (strait pipe ) which consisted of a 3 inch downpipe and a couple sections of flex and a foot of 3 inch pipe. It was loud and just ****ty so I take it off and go to install the 4 inch he had cut off for some reason well the damn thing don't fit. I text him he said the exhaust that was in the bed fit the turbo that was in the toolbox. Well it does but I don't understand why the exhaust outlets are different. The one pulled from the truck is a stock 99.5 plus turbo the one on it looks just like it except the exhaust outlet is way smaller. What damn turbo is on this truck?
