Street Series Cat Back (2003 5.7L Dodge HEMI Ram 1500) – 15787 By Magnaflow

Ready to give your HEMI the voice it was always meant to have? This 3″ MagnaFlow Cat-Back Exhaust System isn’t just here to make noise—it’s here to make beautiful noise. Think deep, smooth, and a little rowdy when you want it to be. Basically, it’s the Sinatra of exhaust systems, but with a lot more horsepower.

This setup comes with a polished stainless steel muffler, a big bold 4″ rolled edge tip, and mandrel-bent 3″ tubing that’s smoother than your uncle’s old pickup lines. Thanks to MagnaFlow’s straight-through, free-flowing core design, this system pumps out more power and torque while reducing backpressure like it’s on a spa day. We’re talking up to 167% better flow compared to those sad, stock chambered mufflers.

The muffler internals are packed tighter than your buddy’s lunchbox with stainless mesh and acoustical fiber—keeping that sweet tone crisp for years without sounding like a busted kazoo over time. And yes, the whole thing’s lap-joint welded and made from stainless steel, so it’ll handle whatever you throw at it: mud, rain, heat, or one too many “just for fun” burnouts.

Installation? No cutting, no welding, and no needing to bribe your neighbor who owns a welder. Just bolt it on, fire it up, and start enjoying your daily commute a lot more.

Fits V8 5.7L Crew Cab Pickup with 78″ bed, single rear side exit on the passenger side.

Backed by MagnaFlow’s Lifetime Warranty, because great sound should last longer than your gym phase. And yes—we beat all advertised prices. Just ask. Or better yet, challenge us—we love a good deal as much as a good burnout.
