Recently, we had a truck in the shop for a conversion, and the owner felt the mufflers were OK. However, to allow the engine to breathe properly, I insisted that the free-flow quiet performance mufflers be installed. Once we removed the old muffler, we could tell it was rusted out, even though it didn't appear to be on the outside. So we cut a window in the side of it, and we were shocked at what we saw; the top section of the internal pipe was rusted through and was lying sideways across the incoming pipe, blocking almost all of the flow. People almost never remove their stacks to make sure their muffler is OK, but by replacing a stock muffler with a quiet performance muffler, you will gain at least 1/4 mpg, which generally translates to saving 1,000 gallons of fuel for every 100,000 miles driven. This also greatly reduces the amount of soot in the engine's oil, along with the iron (FE) particles that are responsible for most engine wear. Our Fleet-Air washable foam air filters also help the engine to breathe and will add fuel mileage and horsepower. Along with the mufflers, they are the first place to start when looking to gain fuel mileage. In most cases, by spendBruce Mallinson ing $500 to $1,000 one is the owner time, you can gain at least of Pittsburgh Power, an 1/2 mpg and 40-plus horseengine performance power and save about shop in Saxonburg, Pa. $5,000 a year or more. 64 | Overdrive | September 2013 ProTips_0913.indd 64 8/27/13 10:03 PM
