Rinehart DBX45 vs Cobra Neighbor Hater: Which Harley Muffler Is Right for You?

When it comes to upgrading your Harley’s sound and style, few mods make as much impact as a new set of slip-ons. Two of the hottest names in the game right now are the Rinehart Racing DBX45 and the Cobra Neighbor Hater. Both are wildly popular, but for very different reasons.

So how do they compare? Let’s break down the sound, performance, build quality, price point, and rider experience—so you can decide which muffler truly fits your ride.

Sound: Deep Tone or Maximum Volume?

This is where these two pipes start to separate.

The Rinehart DBX45 delivers a deep, throaty rumble. Think of it like a finely tuned bass guitar. It’s loud, no doubt, but it’s a controlled kind of loud. The sound is refined, with no rasp or harshness, and it holds up well for riders who plan on logging serious miles.

The Cobra Neighbor Hater, on the other hand, lives up to its name. These are some of the loudest slip-ons on the market. Raw, aggressive, and in-your-face, these pipes are made to turn heads and maybe rattle a few windows. If volume is your top priority, Cobra has you covered.

Performance: Racing Pedigree vs. Street Swagger

Rinehart has roots in racing, and it shows. The DBX45 is tuned for balanced performance and maintains good backpressure. With a proper tune, you’ll get modest horsepower and torque gains, making it a solid pick for performance-minded riders.

Cobra’s Neighbor Haters put all the chips on sound. They’re not tuned for performance, and while you might see slight gains after a retune, the focus is squarely on volume and presence rather than power.

Touring & Comfort

If you’re doing long-haul rides or multi-day tours, the DBX45 is the more comfortable option. The deeper tone produces less drone at highway speeds, making it easier on your ears over time.

The Neighbor Hater, however, can get fatiguing for some, especially at a steady cruise. It’s not just loud in the parking lot. It’s loud everywhere.

Build Quality & Finish

Both pipes are solid, but the Rinehart DBX45 edges ahead in craftsmanship. Stainless steel construction, high-temp ceramic coating, and clean welds give it a premium fit and finish. Plus, it offers more customization options like billet end caps in different styles.

The Neighbor Hater is well-made for the price, with a good chrome or black finish and aggressive slash-cut tips. But when it comes to long-term durability and visual refinement, Rinehart takes the win.

Price Point

Here’s where Cobra flips the script.

The DBX45 runs about twice as much, putting it squarely in the premium category. Meanwhile, the Neighbor Haters provide an unapologetically loud setup for about half the price.

If you’re working with a tight budget and want maximum bang-for-buck in the volume department, Cobra is tough to beat.

Final Thoughts: Which One Should You Buy?

Go with the Rinehart DBX45 if you want:

• A balanced, deep tone that doesn’t wear you out on long rides
• Mild performance improvements with proper tuning
• A refined look and build with more customization options
• Premium craftsmanship and long-term durability

Choose the Cobra Neighbor Hater if you:

• Want the loudest slip-on pipes possible
• Don’t care about tuning or horsepower gains
• Are all about raw, aggressive attitude
• Want a bold look at a more affordable price

In the end, it comes down to rider personality and priorities. The DBX45 is the choice for riders who want power and tone without going over the top. The Neighbor Hater? That’s for the Harley owner who just wants to be heard from a mile away and doesn’t care who hears it.
