Although Ford Powerstroke diesels come with an efficient exhaust method from the workshop, period and testing get proven that there is definitely extent for improvement. Although one might doubt what doable benefits there are to installing a dual exhaust method onto any engine with a unmarried exhaust Issue (as is the context with any turbocharged powerplant), the results asseverate for themselves.
Horsepower
Diesel engines agnate the Powerstroke are capable of generating massive amounts of influence with relatively embryonic job on the contrary Testament one shot be as able as their weakest link. For a Powerstroke, this is the exhaust transaction, which is matchless comprehensive for a inventory engine and isn't representation to base additional potency. Any aftermarket 4-inch exhaust system Testament beget ability over the inventory unit, however capacious duals are the extreme conversation in flow. Unlike naturally-aspirated engines, turbocharged powerplants complete chief with completely unrestricted exhaust flow, which allows the turbo to spool up quicker and constitute also capability. In and of itself, a dual exhaust course is price at least 20 horsepower, and you can add approximately five to seven else whether you include a new turbo down-pipe to go with it.
Fuel Economy
Although installing an aftermarket exhaust system into almost any vehicle will yield a boost in fuel economy, the effect is exponentially greater when applied to diesels. A more free-flowing exhaust makes for efficient combustion and turbo operation, which keep burning fuel inside of the cylinders where it can actually do some good.This is a byproduct of restricted exhaust flow, which causes still-burning diesel fuel to receive caught in the turbo. This condition is exacerbated by aftermarket computer tuners, which inject more fuel to increase horsepower and can quickly lead to destroyed turbos and overheated engines. By itself, a dual exhaust system can decrease EGTs by over 200 degrees, allowing you to inject more fuel for even greater gains in horsepower.
Some people prefer the deeper sound of a dual exhaust over single pipes, but it's a personal preference.
Exhaust Gas Temperature
One of the biggest enemies of any turbodiesel engine is high exhaust gas temperatures (EGT).One test conducted by Diesel Power magazine illustrated that when combined with a new air filter and computer tune, a powerstroke can see gains of more than 100 horsepower at the wheels and fuel economy increases of over 5 miles per gallon. Although this wouldn't be impressive for most vehicles, it's incredible when you take into account that the average powerstroke only yields about 10 to 12 mpg in the city and 14 to 15 on the highway. That's a massive gain of almost 50 percent in fuel economy and three seconds in the quarter mile, all for less than $1,000 and a day's worth of work.
