- Designed for easy clamp-on installation to existing stack piping.
Pros: Premium material and finish provide excellent aesthetic and corrosion resistance.; Reputable brand known for quality automotive components.; Simple installation as a tip, requiring minimal modification to an existing stack pipe.
Cons: This is a stack tip only, not a complete kit, requiring existing stack piping.; The black finish, while durable, can be susceptible to chipping or fading over time with extreme heat exposure.
4. MagnaFlow 17094 Black Series 5 inch Stack Tip: Style Setter
Similar to other premium tips, the MagnaFlow 17094 is strictly an exhaust tip and does not include the necessary piping or mounting hardware to create a functional stack system from scratch. Buyers must already have a 5-inch stack pipe installed on their diesel truck to utilize this product, which is a critical distinction for installation planning.
This product should be bypassed by individuals who require a full stack exhaust system, including the pipe and bed components. It is best suited for those who are satisfied with their current stack’s performance but wish to upgrade its visual appeal with a high-quality, black-finished tip from a respected brand.
- Constructed from stainless steel with a high-temperature black powder coat.
- Features a stylish rolled edge for a finished, premium appearance.
- Simple bolt-on installation to a 5-inch stack pipe.
Pros: Enhances truck aesthetics with a clean, modern black finish.; MagnaFlow's reputation for quality exhaust components.; Durable stainless steel core offers good corrosion resistance.
Cons: Also a tip only, not a complete stack system.; The black coating can show scratches or wear more prominently than polished finishes.
5. Pypes Performance Exhaust SFM62 5 inch Stack Kit: Builder's Pick
Based on owner feedback and material properties, the Pypes Performance Exhaust SFM62 kit, made from aluminized steel, can exhibit susceptibility to rust, especially at the weld points or areas where the protective coating may be compromised during installation or use. This is a common characteristic of aluminized steel compared to stainless steel.
Truck owners who demand the absolute highest level of corrosion resistance and are unwilling to perform occasional maintenance or apply protective coatings should consider investing in a full stainless steel system. This kit is better suited for those who appreciate a more economical option and are prepared for potential long-term surface rust management.

Cons: Aluminized steel construction is prone to rust over time, particularly at welds.; Installation may require some fabrication or additional parts depending on the truck model.
6. Diamond Eye Performance 420005 5 inch Stack Kit: Solid Performer
The Diamond Eye Performance 420005 kit, while a functional and economical choice, is made from aluminized steel, which, as with other similar materials, is more prone to surface corrosion over time compared to stainless steel. This can be a concern for long-term aesthetic appeal and structural integrity in harsh environmental conditions.
Individuals residing in areas with heavy road salt usage or significant exposure to moisture might find this kit requires more frequent inspection and maintenance to prevent rust. Those prioritizing ultimate longevity and minimal upkeep should consider a higher-grade stainless steel option, despite the increased cost.
- Constructed from 5-inch aluminized steel for durable exhaust routing.
- Designed to accommodate various stack tips (sold separately).
- Offers a straightforward path to convert to a stack exhaust system.
Pros: Provides a cost-effective solution for adding a stack exhaust.; Compatible with a broad selection of diesel truck applications.; Good flow characteristics for improved exhaust gas evacuation.
Cons: Aluminized steel construction means less resistance to corrosion than stainless steel.; Some owners report that the fitment may require minor adjustments for certain truck models.

Based on aggregated owner feedback and material properties, the Grand Rock GR50005, with its chrome-plated steel construction, is highly susceptible to rust and pitting if not rigorously maintained. The chrome layer, while visually appealing, can be compromised by road debris, chemicals, or prolonged exposure to moisture, leading to corrosion underneath.
This kit is best skipped by truck owners who are not prepared for a high level of maintenance, including regular cleaning and polishing, to preserve its finish. Those seeking a low-maintenance, set-it-and-forget-it stack exhaust should opt for a solid stainless steel or a properly coated aluminized steel option instead.
- Features chrome-plated steel for a classic, mirror-like finish.
- Designed to stand out with a highly reflective surface.
- Offers a distinct visual appeal for show trucks or enthusiasts.
Pros: Provides a striking, traditional chrome aesthetic.; Known for a bright, polished finish that catches the eye.; Good option for those prioritizing visual style above all else.

Frequently Asked Questions
Are stack exhaust kits legal for diesel trucks?
The legality of stack exhaust kits varies significantly by state and local jurisdiction, as well as by the specific year and emissions standards of your diesel truck. In our research, we found that while some areas permit them, others have strict regulations regarding exhaust height, noise levels, and emissions equipment. It is crucial to consult your local Department of Motor Vehicles or environmental protection agency to ensure compliance before installation.
Do stack exhausts improve diesel truck performance?
In our evaluation of manufacturer specifications, stack exhausts are primarily designed for aesthetic appeal and a distinctive sound. While some kits feature mandrel-bent piping that can improve exhaust flow compared to restrictive stock systems, leading to potential minor gains in horsepower and torque, these improvements are generally not as significant as those from a full performance exhaust system optimized for backpressure and scavenging. The most noticeable ‘performance’ aspect is often the enhanced exhaust note.
What is the difference between aluminized steel and stainless steel stack kits?
Based on our comparison of material specifications, the primary difference lies in corrosion resistance and cost. Aluminized steel kits are typically more budget-friendly but are more susceptible to rust over time, especially in harsh conditions or at weld points. Stainless steel (e.g., T304 or 409) offers superior corrosion resistance and a longer lifespan, but comes at a higher initial investment. We found that stainless steel maintains its appearance and structural integrity better over extended periods.
How difficult is it to install a stack exhaust kit?
The difficulty of installing a stack exhaust kit can vary. We found that most kits require cutting a hole in the truck bed for the stack pipe, which can be a significant step for many owners. Basic kits might involve simple bolt-on assembly for the piping, while more complex setups could require custom fabrication or additional components. Based on aggregated owner feedback, a moderate level of mechanical skill and appropriate tools are generally necessary for a successful installation.
Will a stack exhaust change my truck's sound?
Yes, in our evaluation, a stack exhaust kit will almost certainly change your diesel truck’s exhaust sound. By directing the exhaust upwards, the sound waves are often perceived differently by the driver and bystanders. Many owners report a louder, deeper, and more aggressive tone compared to traditional rear or side-exit exhausts. The specific sound profile will also depend on the muffler (if any), pipe diameter, and engine tuning.
Our Verdict
After extensive research and comparison, the MBRP T5053 5 inch T304 Stainless Steel Stack Pipe Kit emerges as our Top Pick for its unparalleled durability and corrosion resistance, offering a solid foundation for any stack exhaust setup.
