When it comes to upgrading your Harley-Davidson, few modifications deliver the transformative impact of a high-quality exhaust system. Rinehart Racing has built a reputation over two decades for engineering exhaust pipes that balance aggressive sound, performance gains, and craftsmanship. But with multiple configurations and materials available, selecting the right Rinehart Harley pipes requires careful consideration of your riding style, local regulations, and mechanical goals.
Why Rinehart Exhaust Systems Stand Out
Rinehart’s patented True Dual Headpipe design eliminates restrictive crossover piping found in stock Harley systems, optimizing exhaust flow for measurable horsepower gains. Independent dyno tests by Cycle World show 8-12% torque improvements in Twin Cam engines when paired with Rinehart’s 100% stainless steel systems. Unlike cheaper alternatives, their mandrel-bent tubing maintains consistent diameter curves, reducing turbulence that can sap power.
Key Factors When Choosing Rinehart Pipes
-
Compatibility
Verify fitment using Rinehart’s online tool or consult authorized dealers. For example, their Twin Slash series fits 2014-2023 Touring models but requires different headers for M8 engines versus Twin Cam variants. -
Performance vs. Noise Control
Rinehart’s dB levels range from 82 dB (street-legal Cruiser series) to 105 dB (race-oriented Radicals). Riders in noise-restricted areas like California should prioritize EPA-compliant models with removable baffles. -
Material Durability
– 304 Stainless Steel: Resists corrosion and discoloration; ideal for coastal climates (15-year warranty).
– Aluminized Steel: Budget-friendly but requires regular maintenance to prevent rust. -
Aesthetic Preferences
Choose between black ceramic coatings for a stealth look or chrome finishes that match factory Harley styling. The Crossback design adds visual symmetry to bagger models, while slash-cut tips complement café racer builds.
Top Rinehart Models Compared
| Model | Best For | Horsepower Gain | Sound Level | Price Range |
|---|---|---|---|---|
| True Duals | Touring/Heavy Bags | +12% | 92 dB | $1,100-$1,600 |
| Crossbacks | Dyna/Sportster | +9% | 98 dB | $850-$1,200 |
| Slip-Ons w/Baffles | Street Compliance | +6% | 82 dB | $600-$900 |
Installation Insights from Certified Mechanics
While bolt-on kits simplify DIY installation, improper torque settings on header flanges can cause exhaust leaks. Milwaukee Iron Performance recommends:
– Applying anti-seize compound to all threads
– Using a calibrated torque wrench (18-22 ft-lbs for header nuts)
– Re-mapping your ECU within 500 miles to prevent lean conditions
Maintenance for Long-Term Performance
Annual inspections should focus on:
– Checking for heat-induced discoloration near catalytic converters (if equipped)
– Tightening hanger brackets that loosen from vibration
– Cleaning chrome surfaces with non-abrasive polishes like Mothers Mag & Aluminum
Addressing Common Buyer Concerns
“Will aftermarket pipes void my warranty?”
Under the Magnuson-Moss Warranty Act, dealers must prove the exhaust caused a failure to deny coverage. Retain stock parts for service visits if concerned.
“How do I pass emissions tests?”
Opt for CARB-certified Rinehart systems labeled “50-State Legal.” Their OE-style catalysts meet EPA Tier 4 standards without sacrificing flow efficiency.
By aligning your selection with measurable performance metrics and real-world usability factors, Rinehart Harley pipes become more than an aesthetic upgrade—they’re a strategic investment in your bike’s personality and capabilities. For authoritative technical specs, cross-reference Rinehart’s official installation manuals with trusted third-party testing data from sources like J&P Cycles or the Motorcycle Industry Council.
