1. Borla 40348 S-Type Stainless Steel Slip-On Exhaust: Best Overall Sound and Build
The Borla 40348 S-Type slip on exhaust is a top contender for truck owners who want a premium, long lasting system. Built from T304 stainless steel with mandrel bent tubing, it offers excellent flow and durability. Owner feedback consistently praises the sound: deep and aggressive at startup but refined at cruising speeds, with minimal drone. The 4-inch rolled angle-cut tip adds a custom look.
However, this system commands a premium price. If you are on a tight budget, the value may not be there. Also, some owners note that the fit can be tight on certain trucks, requiring patience during installation. We recommend this for those who prioritize quality and sound over cost.
- Aircraft-grade T304 stainless steel construction resists corrosion and lasts for years
- S-Type muffler delivers a deep, aggressive tone without drone on the highway
- Precision mandrel bent tubing for maximum flow and minimal restriction
Pros: Exceptional build quality and corrosion resistance; Rich, balanced sound that improves without being overwhelming
Cons: Higher price point compared to many competitors
2. MagnaFlow 19439 Stainless Steel Slip-On Exhaust: Best Value Stainless Steel
The MagnaFlow 19439 is a popular choice for truck owners seeking an affordable stainless steel upgrade. It uses T409 stainless steel, which is more durable than aluminized steel but not as premium as T304. Owner reviews highlight a deep, throaty tone that is louder than stock but not obnoxious. The straight-through design improves flow, and the polished 3.5-inch tip looks great.
On the downside, the T409 material can develop surface rust over time in harsh winter climates. Also, some users report a slight drone at certain RPMs. If you live in an area with heavy road salt, you might want to invest in a T304 system. This is best for value conscious buyers in moderate climates.
- T409 stainless steel offers a strong balance of durability and cost
- Straight-through perforated core design for increased exhaust flow
- Deep, throaty sound with moderate interior noise
Pros: Very good value for a stainless steel slip on; Durable enough for daily driving and light off-road use
Cons: T409 is less corrosion resistant than T304, may show rust in salt belt areas
3. Flowmaster 817483 FlowFX Slip-On Exhaust: Best Aggressive Sound
The Flowmaster 817483 FlowFX slip on is for truck owners who want a loud, aggressive exhaust note. It uses aluminized steel, which is less expensive but more prone to corrosion over time. Owner feedback indicates a very deep rumble at idle and a roar under acceleration, though some interior drone is present on the highway.
If you live in a dry climate or keep your truck garaged, the aluminized steel can last several years. However, for those in snowy or coastal areas, stainless steel is a better investment. This system is best for those who prioritize sound over longevity and are willing to replace it down the road.
- Flowmaster's signature aggressive sound with moderate drone
- Mandrel bent 3-inch tubing for improved flow
- Includes all necessary hardware for bolt-on installation
Pros: Loud, aggressive tone that muscle truck enthusiasts love; Easy bolt-on installation with included clamps and hangers
Cons: Aluminized steel may rust faster than stainless in wet conditions
4. Gibson 615491 Superflow Slip-On Exhaust: Best for Towing and Hauling
The Gibson 615491 Superflow slip on is engineered for trucks that work hard. It focuses on increasing low-end torque, which is beneficial for towing and hauling. Owner reviews mention a solid improvement in throttle response and a deep, mellow tone that doesn’t drone excessively. The installation is straightforward with all necessary hardware included.
However, the aluminized steel is less durable than stainless, especially in corrosive environments. Some owners also note that the sound can be a bit quiet for those seeking an aggressive note. If you primarily use your truck for towing and want a modest power gain without breaking the bank, this is a solid choice. Skip it if you want a loud, showy exhaust.
- Designed to improve low-end torque for towing and hauling
- Large 4-inch polished stainless steel tip for a custom look
- Includes all hardware and instructions for straightforward installation
Pros: Noticeable low-end torque improvement reported by many owners; Deep sound that is not overly loud under load
Cons: Aluminized steel construction may not last as long as stainless
5. Corsa 21935 Sport Performance Slip-On Exhaust: Best No-Drone Technology
The Corsa 21935 Sport slip on is a premium option for truck owners who demand a drone-free experience. Its RSC technology cancels out unwanted frequencies while preserving a sporty tone under throttle. Owner feedback is overwhelmingly positive about the lack of drone, even on long trips. The T304 stainless steel ensures long life, and the polished double wall tip adds a refined look.
That said, the cost is significantly higher than many competitors. If you are budget conscious, this may not be the best pick. Also, some owners find the sound too mild for their taste. This system is ideal for those who spend a lot of time on the highway and want a quiet cabin without compromising on performance.
- Corsa's patented Reflective Sound Cancellation (RSC) eliminates drone
- T304 stainless steel for maximum corrosion resistance
- Aggressive sound under acceleration, quiet at cruise
Pros: Zero drone at highway speeds, even with aggressive driving; Premium T304 stainless steel construction with a lifetime warranty
Cons: High price point may not fit all budgets
6. MBRP S5223AL Aluminized Slip-On Exhaust: Budget Friendly Pick
The MBRP S5223AL is a no-frills slip on exhaust that delivers good sound and performance at a low cost. It uses aluminized steel, which keeps the price down but compromises on longevity. Owner reviews note a deep, aggressive tone that is louder than stock but not overbearing. Installation is straightforward with all clamps and hangers included.
However, the aluminized steel can start to show rust within a year in harsh climates. If you live in an area with heavy snow or road salt, this system may not last long. It is best for those on a tight budget who don’t mind replacing the exhaust after a few years, or for trucks that are not daily drivers in winter.
- Affordable price point for a complete slip on system
- Mandrel bent tubing for smooth flow and better sound
- Bolt-on design with included hardware for easy installation
Pros: Very budget friendly without sacrificing sound quality; Deep tone that improves over stock
Cons: Aluminized steel is prone to rust, especially in salt belt states
7. AWE 3015-33020 0FG Exhaust Slip-On: Best Modern Design
The AWE 3015-33020 0FG slip on exhaust stands out with its diamond black tip and modern aesthetic. It is constructed from T304L stainless steel and includes drone-canceling technology. However, owner feedback indicates that the sound is relatively subtle compared to other systems, with a modest increase in volume and a refined tone.
The main drawback is the high price relative to the performance and sound improvement. Many users feel it offers less bang for the buck. Additionally, the fitment can be tricky on some truck models, requiring minor adjustments. This system is best for those who prioritize a clean, OEM+ look and a quiet cabin, and are willing to pay a premium for aesthetics.
- Unique diamond black tip finish for a stealthy look
- T304L stainless steel with a lifetime warranty
- Drone-canceling technology for a refined sound
Pros: Stylish design with a black tip that hides dirt and soot; Good build quality with a lifetime warranty
Cons: Expensive for the performance gains; sound is subtle
Frequently Asked Questions
What is a slip on exhaust and how does it differ from a cat-back system?
A slip on exhaust replaces only the muffler section, connecting to the existing pipes with clamps or flanges. A cat-back system replaces everything from the catalytic converter back, including pipes and muffler. Slip ons are easier to install and less expensive, but may offer smaller power gains.
Will a slip on exhaust void my truck's warranty?
In most cases, a slip on exhaust will not void your warranty unless it directly causes a failure. However, some dealers may deny claims related to the exhaust system. Check your warranty terms and consider using a system that retains factory emissions components.
How much louder is a slip on exhaust compared to stock?
It varies by design. Systems with straight-through mufflers or aggressive chambers can be significantly louder, while others offer a moderate increase. Owner reviews and sound clips can help gauge the loudness. Most slip ons are louder than stock but not obtrusive.
Can I install a slip on exhaust myself?
Yes, most slip on exhausts are designed for bolt-on installation with basic hand tools. You will need jack stands, wrenches, and possibly penetrating oil for rusted bolts. Many owners report installation times of one to two hours.
Will a slip on exhaust improve fuel economy or horsepower?
Manufacturers often claim modest gains of 5-10 horsepower and slight fuel economy improvements due to reduced backpressure. In real world conditions, the gains are usually minimal and may not be noticeable. The primary benefit is sound and weight reduction.
Our Verdict
After research and comparison, the Borla 40348 S-Type takes the top spot for its exceptional build quality, deep sound, and long term durability. For those seeking a balance of value and performance, the MagnaFlow 19439 is our runner up, offering stainless steel construction at a more accessible price point.
