Dual Split Rear Exit Cat Back 2004-2005 HEMI Ram 1500 – 15863 By Magnaflow

Let’s be honest—your 5.7L HEMI already makes a statement. But if you’re still rocking the stock exhaust, that statement might be more “library quiet” than “bar fight in a saloon.” Time to fix that.

This Magnaflow cat-back exhaust system for the 2004–2005 Dodge Ram 1500 (Crew or Extended Cab, short or long bed) is built to turn your truck’s whisper into a full-throated, head-turning roar. It’s crafted entirely from 3″/2.5″ mandrel-bent stainless steel, so the only thing that’ll rust is your neighbors’ envy. The heart of the beast is a polished 5x8x24″ muffler packed with high-density acoustic fiber and a straight-through stainless core—delivering that deep, smooth tone Magnaflow is famous for. It’s like Barry White under your truck, but with horsepower.

Speaking of power, this setup doesn’t just sound good—it performs. Magnaflow’s design cuts backpressure, improves exhaust scavenging, and boosts both torque and horsepower. It outflows stock mufflers by up to 167% (yes, we said one-six-seven percent)—so your engine works less and you get more vroom-vroom for your buck-buck.

Installation is a breeze. No cutting, no welding, no tears. Everything you need is in the box—including hardware and a manual you’ll probably only half-read (don’t worry, it’s easy).

Key Features:

• 100% stainless steel construction

• 3″/2.5″ mandrel-bent tubing

• Dual 3.5″ polished tips, split rear exit

• Lifetime warranty

• Deep tone, more power, better looks

• Fits 2004–2005 Ram 1500 with 5.7L HEMI (Crew/Ext. Cab, short or long bed)

Get it, install it, floor it. Your HEMI deserves to breathe easy and growl proud.
