01 Muffler
Anyhow, have 01 SD, 5.4, 3.73, 4X4, EC, SB and have been very pleased with truck since I placed the order to have her built and drove off the dealers lot. This truck will be my long term driver, plans to to keep her for a long time, 20 years plus. As I am approaching the loan payoff I would like to consider a new exhaust if my question has a positive outcome.
Question? Myth or fact will the "right" exhaust / muffler give me a HP and or gas milage boost? If so what would you that right combo be?
TIA
