The Flowmaster 17233 is a chambered muffler that gives your vehicle a very deep and mellow tone. It’s the perfect balance of sound and refinement. This system provides a noticeably louder and deeper pitch than stock, without being obnoxious. Just a pleasing rumble at idle, and a roar when you get on the throttle.

Features of the Flowmaster 17233 Exhaust
What makes the Flowmaster 17233 stand out from other exhausts? Let’s look at some key features:
- Chambered muffler design – This gives the 17233 its trademark deep tone that burbles at idle and roars under acceleration. The chambers dampen sound waves differently than a typical muffler.
- Mandrel-bent tubing – Maintains smooth exhaust flow by preventing tubing from becoming crushed or kinked during bending. Mandrel bending allows maximum exhaust velocity.
- Stainless steel construction – The 17233 system features 16 gauge aluminized steel or stainless steel tubing to prevent corrosion. Stainless also helps it last longer than ordinary steel.
- Performance gains – By improving airflow, the 17233 adds horsepower gains of 7-15 HP, depending on the application. The exact gains depend on your vehicle’s engine size and mods.
- Easy installation – Bolt-on design includes all necessary hardware and hangers for hassle-free installation. Detailed instructions walk you through each step. An experienced DIY’er can install it in 2-3 hours.
So in summary, the materials, construction, and chambered design all contribute to the Flowmaster sound and performance. It’s a complete mandrel-bent cat-back system engineered for easy installation and lasting durability.
The Flowmaster Sound
One of the biggest reasons people choose the Flowmaster 17233 exhaust is for the sound. Installing this system completely transforms the tone from your tailpipes.
Here’s an overview of what to expect:
- Deeper, fuller exhaust note than stock
- Classic Flowmaster rumble at idle
- Moderate interior resonance while cruising
- Aggressive growl when accelerating hard
- No excessive drone at highway speeds
It’s not as loud as Flowmaster’s SuperSeries or Delta Force line, but definitely louder than stock. The sound level is just right for someone who wants an upgraded exhaust without being overbearing. It turns heads, especially on trucks and muscle cars, without droning or drawing negative attention.
If you find the 17233 too tame, Flowmaster also offers the 17234 model. It features the same construction but with a more open chambered design for increased volume.
Materials and Construction
The Flowmaster 17233 comes fully constructed and ready to bolt directly onto your vehicle. Here are the main components:
- Aluminized or stainless steel tubing – 16 gauge steel tubing is mandrel bent for smooth exhaust flow. Stainless models offer increased corrosion resistance.
- Chambered muffler – The main muffler features Flowmaster’s signature chambered and louvered design. Gives the 17233 its deeper tone.
- Moderate sound absorption – Provides muffling while still allowing exhaust resonance and Flowmaster’s signature tone.
- Stainless steel tips – 3.0″ stainless tips look clean and polished. Embossed with Flowmaster name and logo.
- Hardware and hangers – Includes clamps, brackets, and hangers for secure installation. Uses factory mounting points.
The materials and construction are high quality to prevent rusting and cracking. Everything is covered by Flowmaster’s limited lifetime warranty.
As long as you’re pairing the 17233 with the proper headers and front pipes, this kit contains everything you need for installation. No extra parts required.
Exhaust System or Muffler Only?
The Flowmaster 17233 is available as either a complete exhaust system or a muffler-only configuration:
- Complete exhaust – Replaces everything from the catalytic converter back. Includes pipes, muffler, and tips. This is the easiest option for most DIY installations.
- Muffler only – Just replaces the OEM muffler section while reusing the existing piping. Requires some fabrication skills to properly fit the new muffler.
Unless your current exhaust pipes are in good shape, I recommend going with the full system. It bolts up directly to the catalytic converter and includes all flanges, hangers, clamps, and piping. The complete system guarantees fitment while the muffler-only setup can be tricky to fabricate correctly.
Performance Benefits of the 17233 System
While the Flowmaster 17233 excels at giving your vehicle an upgraded exhaust note, it also provides performance improvements:
- Horsepower gains – Expect between 7-15 HP increase, depending on engine size and existing mods. Simply from improved airflow and reduced backpressure.
- Improved throttle response – The less restrictive 17233 allows exhaust gases to escape easier, giving crisper throttle response.
- Increased MPG – By reducing exhaust backpressure, gas mileage can improve slightly. Every little bit helps!
- Sound level tuning – Provides ideal volume and tone when paired with proper headers. Avoid “drone” issues and unpleasant tones.
For turbocharged vehicles or heavily modded muscle cars, a Full Flowmaster exhaust may offer even bigger power gains. But the 17233 strikes a great balance for the average truck or car owner looking for better performance and sound.
What’s Included in the Kit
The Flowmaster 17233 comes neatly packaged with everything required for installation:
- Chambered muffler section
- Full exhaust piping or inlet/outlet pipes
- 4.0″ stainless steel tip
- Flanges, clamps, hangers, and hardware
- Complete mounting kit to attach to stock locations
- Detailed step-by-step instructions
- Flowmaster window decal and badge
Unless you have a very customized vehicle, the 17233 kit should come with all exhaust components and hardware. Pay close attention to the instructions and diagrams. Provided you have some mechanical ability and basic tools, the average person can install this system themselves over a weekend.
Cost Comparison
So how much will this upgrade set you back? Let’s compare the Flowmaster 17233 cost to other exhaust options:
- Stock replacement exhaust – $200 to $400 range
- Basic muffler shop upgrades – Around $300 to $500+ for pipes and muffler
- Budget aftermarket system – $400 to $700 range
- Flowmaster 17233 – Approximately $550 to $950 depending on vehicle

Required Vehicle Modifications
Fortunately, no permanent modifications to your engine or body are required to install the Flowmaster 17233 exhaust. It bolts up to factory mounting points in place of your stock system.
Some tips on compatibility:
- Ensure proper fitment by looking up exact make/model/year applications.
- May require an adapter pipe if switching exhaust layouts (e.g. dual to single exhaust).
- Aftermarket headers, lifted vehicles, or custom work may require custom exhaust fabrication.
- Check adequate clearance around spare tire, fuel and brake lines, etc.
As long as you reference the correct 17233 kit for your vehicle and have an unaltered stock exhaust layout, there should be zero required modifications. It’s designed for easy bolt-on replacement.
Different Finishes and Styling
The Flowmaster 17233 comes standard with a polished stainless steel tip. This matches most vehicle styles and provides corrosion resistance.
Optional finishes include:
- Black tip – More discrete, matches blacked-out vehicle styles.
- Chrome tip – Brilliant show-quality shine if you want flashy.
- Blue or red tip – Colored for custom looks, available in electric blue or red powdercoat.
So beyond the standard stainless, you can choose a finish that matches your vehicle’s personality – stealthy, flashy, or colorful. Black and chrome are most popular.
Effects on Fuel Efficiency
Does adding an aftermarket exhaust like the Flowmaster 17233 help or hurt your gas mileage?
The effect is usually small, but every MPG counts. Here’s an overview:
- Slight MPG gains – By reducing backpressure, efficiency can improve ~1-3 MPG for most vehicles.
- Power gains offset – Extra horsepower may lead to “lead foot”, lowering MPG.
- Weight reduction – Lighter than heavy stock exhaust components.
- Mileage loss if noisy – Constantly revving to hear the exhaust can waste gas.
- Driving style matters – Aggressive driving negates any MPG gains. Gentle highway cruising sees the most benefit.
In summary, you may see a slight mileage improvement around town, but aggressive driving will probably offset it. Consider the 17233 more for sound and power rather than fuel economy. But any MPG gain is a nice bonus.
Conclusion
There are lots of mediocre exhausts that fail to deliver on their claims. That won’t happen with the Flowmaster 17233. This chambered system provides noticeable horsepower and aesthetic upgrades. The sound clips speak for themselves – that signature Flowmaster rumble is unmatched. For anyone looking to add some engine attitude without breaking the bank, the 17233 is an excellent choice. The throaty growl will turn heads whether cruising Main Street or the off-road trails.
