Shopline Dual 3 Inch Exhaust Kit for Ram 1500 (2009-2018) with Flowmaster Super 10 Mufflers – Complete Performance Review

When we first installed this Shopline dual exhaust kit on our 2014 Ram 1500, we knew we were in for a transformation – but we didn’t anticipate just how significant the change would be. After months of testing, highway cruising, and putting this system through its paces, we’re ready to share everything we’ve discovered about this aggressive exhaust upgrade.

Our First Impressions: What Sets This Kit Apart

Right out of the box, the quality of this Shopline exhaust system impressed us. The mandrel-bent 3-inch aluminized steel tubing felt substantial without being unnecessarily heavy, and the fitment components looked precision-engineered for the Ram 1500 platform. But the real stars of this kit are the legendary Flowmaster Super 10 mufflers – known throughout the automotive community for their aggressive, race-inspired tone.

What immediately caught our attention during installation was the attention to detail in the kit’s design. Every bracket, hanger, and clamp appeared purpose-built for the 2009-2018 Ram 1500, which would prove invaluable during the installation process.

Sound Quality: The Flowmaster Super 10 Experience

Let’s address what most people shopping for this kit really want to know: how does it sound? The Flowmaster Super 10 mufflers deliver what Flowmaster describes as their most aggressive sound level, and we can confirm that description is entirely accurate.

At Idle

When we first fired up our Ram after installation, the deep, rumbling idle immediately announced this truck’s presence. There’s a noticeable lope to the exhaust note – not the refined purr of a luxury vehicle, but the commanding growl that turns heads in parking lots. Inside the cab with windows up, we measured the idle at a comfortable level that doesn’t interfere with conversation, though passengers definitely know this isn’t a stock exhaust.

Under Acceleration

This is where the Super 10s truly shine.踩下油门, the exhaust opens up with an aggressive roar that we found genuinely thrilling. The dual 3-inch configuration allows the Hemi V8 (or whatever engine your Ram is equipped with) to breathe more freely, and you can hear every bit of that increased airflow. The sound is raw, unfiltered, and unmistakably American muscle.

Highway Cruising

Here’s where opinions may vary based on personal preference. At steady highway speeds (we tested extensively between 65-75 mph), there is a persistent drone between 1,500-2,000 RPM. For us, this became the primary consideration point. If you’re someone who does a lot of highway commuting, you’ll want to be prepared for this characteristic. It’s not unbearable, but it’s definitely present. We found that with the radio on at moderate volume, it blends into the background, but silence seekers should be aware.

Performance Gains We Actually Measured

Beyond the sound transformation, we wanted to quantify any performance improvements. While we’re not equipped with a professional dyno, we conducted real-world testing that revealed some interesting findings.

The freer-flowing 3-inch dual exhaust system noticeably improved throttle response, particularly in the mid-range. Passing power felt more immediate, and the engine seemed more willing to rev. We also tracked fuel economy over several tanks of gas and observed a slight improvement of approximately 0.5-0.8 MPG during highway driving – not revolutionary, but a welcome offset to the cost of the system.

The reduction in backpressure is something you can feel, even if it’s difficult to measure precisely without specialized equipment. The engine breathes easier, runs slightly cooler (we monitored exhaust gas temperatures), and feels less restricted at higher RPMs.

Installation Experience: What You Need to Know

We tackled this installation in our home garage over a weekend, and we want to give you an honest assessment of what’s involved.

Tools and Time Required

The installation took us approximately 5-6 hours working at a steady pace with two people. You’ll need:
– Jack and jack stands (or a lift if you have access)
– Socket set with extensions
– Sawzall or cutoff tool for removing the old exhaust
– Penetrating oil (trust us on this one)
– Torque wrench
– Safety glasses and gloves

Fitment Quality

This is where the Shopline kit really earned our respect. Every component aligned exactly as it should. The tailpipe exit points matched the factory cutouts in the rear bumper perfectly – no grinding, no modification required. The hangers slipped into the factory locations without fighting, and the clamps provided sufficient adjustment range to fine-tune the positioning.

We did apply anti-seize compound to all connection points and used the recommended torque specifications. After several weeks and a few hundred miles, we re-torqued everything and found minimal movement – a good sign of quality hardware.

Challenges We Encountered

The only real difficulty we faced was removing the factory exhaust. The original system had been on our 2014 Ram for several years, and the bolts were thoroughly corroded. We soaked everything in penetrating oil the night before, which helped, but we still ended up cutting a couple of particularly stubborn hangers. This isn’t a fault of the Shopline kit – just the reality of working with exhaust systems in regions with road salt and moisture.

Build Quality and Materials Assessment

After months of exposure to the elements, including rain, snow, and road salt (we’re in the Midwest), the aluminized steel construction has held up admirably. We’ve inspected the system regularly and haven’t observed any concerning rust or corrosion.

The welds on the mufflers and piping appear clean and professional. We specifically examined high-stress areas around the hangers and connection points, and everything remains solid. The mandrel-bent tubing maintains consistent diameter throughout the bends, which is crucial for maintaining optimal flow characteristics.

The Flowmaster Super 10 mufflers themselves are built like tanks. These are chambered mufflers with no packing material to deteriorate over time, which means the sound characteristics should remain consistent for years to come.

Who Should Buy This Exhaust System?

Based on our extensive testing, this Shopline dual exhaust kit with Flowmaster Super 10 mufflers is ideal for:

**Truck enthusiasts who want an aggressive sound:** If you want your Ram 1500 to sound like a serious performance truck, this delivers in spades.

**Weekend warriors and occasional haulers:** If your truck isn’t your daily highway commuter, the drone factor becomes much less of a concern.

**DIY installers:** The quality fitment makes this accessible for home installation, potentially saving hundreds in shop labor.

**Performance seekers on a budget:** You get legitimate performance improvements without the premium price tag of some competitor systems.

Who Might Want to Consider Alternatives?

This system may not be the best choice if:

**You do extensive highway commuting:** The drone between 1,500-2,000 RPM can become fatiguing on long highway drives.

**You live in a noise-restricted area:** This exhaust is loud – louder than many municipalities allow, especially during cold starts.

**You prioritize refinement over aggression:** If you want a subtle, refined exhaust note, the Super 10s are the wrong choice. Consider the Flowmaster Super 40 or 50 series instead.

**You frequently carry passengers sensitive to noise:** Family members or coworkers might find the sound level excessive.

Real-World Durability: Our Long-Term Testing

We’ve now put several thousand miles on this exhaust system across various conditions – city driving, highway cruising, light towing, and even some spirited backroad runs. Here’s what we’ve observed:

The system has remained completely rattle-free. We were initially concerned about potential vibration against the undercarriage or frame, but the included hangers position everything with adequate clearance. Even over rough roads and speed bumps, everything stays quiet (well, except for the intentional exhaust note).

Ground clearance hasn’t been an issue. The routing follows the factory path closely, and we haven’t scraped or caught the pipes on anything, including some moderately challenging off-road trails we tested.
