Since the first exhaust pipe, the aftermarket has found ways to beat factory design, performance or appearance. Although most modern pickup exhausts are comparably free-flowing by even 20-year-old standards, there is usually some room for improvement, and Corsa Commercial’s exhausts are a way to gain a few benefits without adding a lot of fanboy noise.
We didn’t dyno the change on this pickup nor gather long-term fuel economy data yet, but we can tell you this piece looks better, feels incrementally stouter, took almost 15 pounds off the truck’s weight and, since our only drive so far is empty highway cruising at about 1,300 rpm, any fuel economy gain is measured in tenths.
It sounds much better outside and has a deeper purr in the cab, but there’s no droning or booming, and the hands-free needs no volume adjustment. Installation took than half an hour — what we might have saved using a lift was eaten up with camera work, using everyday hand tools. Retail prices on Corsa Commercial systems run from $550, and there’s a discount for fleets purchasing multiple units, and a 10-year limited warranty.
The included instructions are succinct, but as the spring-under shows, our short-wheelbase test truck is quite a bit lower than stock, so cutting the pipe above the diff was the easiest extraction method.
The spherical clamp from the stock system is reused. With the lock tab from the stock pipe gone, it’s much easier to fasten if rotated 180 degrees as shown. Corsa recommends rechecking the fasteners after the truck’s been driven for a heat cycle and cooled down.
