A few years ago, I fell into an argument with an old roommate—an automotive engineer by trade—over some potential modifications of my 2005 Pontiac GTO. For a brief moment, I considered bolting long-tube headers and full exhaust to the 6.0-liter LS2 V-8, netting a predicted gain of between 20 and 30 horsepower. He argued it wasn’t worth the effort and money involved; 30 hp is a 7.5 percent gain, what difference can that make? Well, meet the 2021 Subaru Crosstrek Sport.
