Re: Taking the Plunge, first performance modifications
Go with the full 4" exhaust.. If you had bought that engine from International rather than Ford it would already have the 4" and been pushing 300 hp vs 250 so I'm told.. I could not believe the difference in go just from that swap when towing. Can't say I really saw a difference in mileage when not towing.
2002 Ford F350 Lariat 4X4 S.C, 7.3L, 373 ls off road, 8ft box, 4" exh but stock for now
