Revving Up Nostalgia
Every year, automobile enthusiasts and vintage car aficionados gather in Louisville, Kentucky, for the highly anticipated NSRA Street Rod Nationals. This event is a celebration of automotive craftsmanship, where classic car owners and builders from around the nation come together to showcase their meticulously restored and customized street rods. The show offers a unique blend of nostalgia and innovation, as attendees are treated to a mesmerizing display of vintage vehicles, creative modifications, and impressive engineering.
AFTER-CAT INSTALL
The white ’99 Silverado was beginning to show the wear and tear of fighting the highway wars the last few years. The once proud and pampered show truck—a standard cab shortbed with matching cab-high camper shell—hadn’t spent much time in daily service until recent years, but now it bore its share of dings, dents and scratches. It was obvious that the 50,000 miles on the odometer hadn’t done the 5.3-liter V-8 much good. Part of the reason for the dissipated performance was the exhaust system, a very tired, less-than-top-quality aftermarket after-cat that had started banging, squeaking and leaking.
Installing a new after-cat from MagnaFlow was at the top of this owner’s agenda. He acquired a MagnaFlow (part No. 15617) polished stainless steel after-cat performance system for his Chevy, and because he’s in the automotive business and has a lift at his own facility, all he had to do was enlist the help of a colleague experienced in exhaust system installs to lend a hand with the hookup.
WE HAVE A WINNAH!
This beauty is easy on the eyes. It’s lightning-quick on the throttle and a lot of fun to cruise around town in—but it wasn’t always that way.

Unmatched Valve Control
The lifeblood of any performance engine is valve control, and this kit delivers in spades.

The coil bind at 1.070″ is engineered to perfection, giving you confidence no matter how hard you push that throttle.
Whether you’re running a nasty N/A stroker, a big-boost turbo build, or just a stout cammed street car, keeping your valves in check at high RPM is crucial. And this dual-spring setup? It’s like having a bouncer for your valvetrain—rowdy but controlled.

Oh, and did I mention it’s all designed to work seamlessly with stock rocker arms? That’s right, no extra surprises or costly modifications needed. This is a drop-in solution for 15° LS heads, and if you’ve got LS7 heads, just toss in a .045″ shim, and you’re good to go.
