3. Pypes Performance Exhaust Cutout Kit: Best Value
In our evaluation, the Pypes Performance Exhaust Cutout Kit offers a solid balance of cost and functionality. Based on owner feedback and the spec sheets, the manual cable system is reliable and easy to install. The aluminized steel provides decent corrosion protection for most climates, making it a practical choice for budget-minded truck owners.
However, the manual operation can be inconvenient as it requires physically accessing the valve under the truck. This kit is not ideal for those who want the convenience of remote control or who frequently switch between open and closed modes. Skip this if you have a lowered truck or limited underbody access.

4. MagnaFlow Exhaust Cutout Kit: Premium Build
Our research indicates that the MagnaFlow Exhaust Cutout Kit is built to last, with heavy-duty 304 stainless steel that withstands rust and high heat. Owner feedback praises its smooth valve operation and low-profile design that avoids ground clearance issues. The included remote adds convenience.
However, the higher cost and sometimes complex installation make it less accessible for casual users. This kit is not the best choice for those on a tight budget or who want a simple DIY install. Consider this if you prioritize long-term durability and have the budget to match.

However, there are occasional reports of motor issues over time, and installation can be more involved than clamp-on kits. This product is not ideal for those looking for a simple bolt-on solution or who prioritize long-term reliability over peak performance. Skip if you prefer a manual system or have a tight installation space.
- Mandrel-bent tubing for optimal flow.

However, the motor performance is not as strong as competitors, and some users report slower operation. This kit is not ideal for those who need a robust, long-lasting system or who frequently operate the cutout in harsh conditions. Skip this if you can accommodate a larger, stainless steel option.
- Compact valve design for tight spaces.
- Ceramic coating for heat and corrosion resistance.
- Includes remote control and wiring.
Pros: Small footprint fits where others won't.; Ceramic coating offers decent protection.; Remote control included.
Cons: Mild steel core can rust if coating chips.; Motor reported as less powerful by some users.
Frequently Asked Questions
What is an exhaust cutout kit and how does it work?
An exhaust cutout kit is a valve installed in the exhaust system that allows you to bypass the muffler and other restrictions, directing exhaust gases straight out. It can be manually operated (cable or lever) or electronically controlled via a remote switch. When open, it increases exhaust flow and sound; when closed, the system returns to normal operation.
Are exhaust cutout kits legal?
Laws vary by location. In many areas, open exhaust cutouts are illegal on public roads due to noise regulations. Some kits are designed for off-road or track use only. Always check local laws before installation. Using a cutout that can be closed may help comply with noise ordinances when needed.
Will an exhaust cutout affect engine performance?
When open, an exhaust cutout reduces backpressure, which can improve horsepower and torque in some engines, especially those with forced induction or high-performance builds. However, on stock engines, gains may be minimal and could potentially reduce low-end torque. It is best used with a tune for optimal results.
How difficult is it to install an exhaust cutout kit?
Installation difficulty varies by kit and vehicle. Manual cutout kits are generally easier and can be clamped on. Electric kits require wiring for power and remote receiver, which may be more complex. Basic mechanical skills and tools are sufficient for most kits, but some may require cutting and welding. Professional installation is recommended for those not comfortable with exhaust work.
What size exhaust cutout do I need?
Choose a cutout that matches your exhaust pipe diameter (e.g., 2.5-inch or 3-inch). Using a smaller size can create a restriction, while a larger size may require adapters. Measure your exhaust pipe outer diameter before purchasing. Most kits are available in common sizes.
Our Verdict
After thorough research and comparison, the QTP Electric Exhaust Cutout System earns our top pick for its reliable motor, stainless steel construction, and included remote. For a more budget-conscious option, the Pypes Performance Exhaust Cutout Kit offers solid manual operation at a lower cost. Both provide excellent value depending on your needs and preferences.
