I Incorporated both of these flex pipe sections after the y to make the perfect curve to a new stainless steel exhaust system. I am extremely satisfied and happy with this product after ordering a few others.

5 stars on these flexible exhaust connectors. Size is right on the dot and the short flex pipe is pliable but not weak where it lets pipes move around too much. Great for when you are building a new system where clearance is tight and you don't want the exhaust flexing to the point of contacting frame members. Also, no problems with TIG welding the stainless steel. No weird impurities in the puddle or odd looking welds. Very happy with these.

These worked great on my custom exhaust. Welded nicely and allowed any vibrations from the engine to be isolated.

Nice stainless braid with a corrugated flex core. I want to love them, but wish the inside wasn't corrugated and smooth instead. For a 3" flex- I'm sure that back pressure won't be an issue, but don't like having the dips in the flex to hold moisture, carbon etc. That being said- I'm sure these will lower vibration through the exhaust by allowing flex between my header collector and pipes. Note- sharp edges and NO room to clamp (why would you) so must be welded in place.

The QYFNB Exhaust Flex Pipe (3" x 5.9") is a high-quality, heavy-duty exhaust flex tube designed for automotive use. It's made from 304 stainless steel and features double-braided construction for durability and flexibility. Below is a detailed review based on its features, performance, and usability.Key Features:3" Diameter and 5.9" Length: The 3-inch diameter and 5.9-inch length provide a versatile fit for most automotive exhaust systems, whether you're working on a car, truck, or other vehicles. It’s suitable for replacing or upgrading existing exhaust flex pipes in a variety of setups, offering flexibility and the ability to absorb movement and vibrations.304 Stainless Steel Construction: This exhaust flex pipe is made from 304 stainless steel, a material known for its excellent resistance to corrosion, rust, and high temperatures. This makes it ideal for withstanding the harsh conditions within the exhaust system, such as high heat, pressure, and exposure to moisture or road salt.Double-Braided Design: The double-braided construction provides enhanced strength, durability, and flexibility. The inner braid helps resist kinking, while the outer braid adds structural integrity, ensuring that the flex pipe maintains its shape and function even under stress or movement.Universal Fit: The flex pipe is designed to be universal, making it compatible with a wide range of vehicles and exhaust systems. It can be used in various applications, such as on exhaust pipes, catalytic converters, or mufflers. The flexibility of the pipe makes it easy to install, especially in areas where movement or vibration needs to be absorbed.Heavy-Duty Performance: Built for heavy-duty applications, this exhaust flex pipe is made to last. It’s designed to handle high levels of exhaust pressure and temperature while maintaining its flexibility and integrity over time. The heavy-duty design ensures long-lasting performance, even in demanding environments.Pack of 2: The set comes with two flex pipes, providing extra value and convenience if you need to replace or upgrade multiple sections of your exhaust system at once.Performance:Vibration Dampening: The primary purpose of an exhaust flex pipe is to absorb vibrations and movement between different parts of the exhaust system. The double-braided construction and flexible design of the QYFNB exhaust pipe perform well in this regard, effectively reducing stress on exhaust joints and preventing damage to the system.Durability: The 304 stainless steel material offers outstanding resistance to heat, rust, and corrosion. This ensures the pipe can withstand the constant exposure to high temperatures and exhaust gases without degrading over time. This durability is critical for long-term reliability, especially in vehicles that see a lot of driving in various weather conditions.Ease of Installation: The universal design makes it easier to install on most vehicles without requiring specific adapters or modifications. Whether you’re a professional mechanic or a DIY enthusiast, the flexibility and straightforward fitment make it an appealing option for both professional installations and at-home repairs.Temperature Resistance: The stainless steel construction can handle the high temperatures typically seen in exhaust systems, ensuring that the flex pipe doesn’t degrade or fail prematurely under heat stress.Pros:Durable 304 stainless steel construction for excellent rust and corrosion resistance.Double-braided design offers added strength and flexibility.Universal fit makes it compatible with a wide range of exhaust systems.Heavy-duty performance suitable for absorbing vibrations and handling high exhaust pressures.Pack of 2 provides great value for money, allowing for multiple repairs or upgrades.Easy installation due to its flexible design.Cons:Size Limitations: The 3-inch diameter may not be suitable for all exhaust systems, especially those with larger or smaller diameter pipes. Always check the compatibility with your vehicle's exhaust before purchasing.Potential for Overstretching: If subjected to excessive movement or tension, the flex pipe might overstretch, so it’s essential to ensure proper installation to prevent this from happening.Conclusion:The QYFNB Exhaust Flex Pipe is a reliable, durable, and flexible solution for anyone looking to replace or upgrade their exhaust system. The use of 304 stainless steel ensures long-term corrosion resistance, while the double-braided design adds strength and flexibility, making it ideal for dampening vibrations and absorbing movement within the exhaust system. Its universal fit and heavy-duty performance make it suitable for a wide variety of applications, from cars to trucks.For those looking for a dependable exhaust flex pipe, this product offers excellent value, especially with the two-piece pack. It’s a great option for both professionals and DIYers looking to improve or maintain their vehicle’s exhaust system. However, it’s essential to ensure that the 3-inch diameter is the right size for your specific exhaust system before purchasing.

These flex pipes should do the job on my custom SS exhaust system. They are 304 stainless, which shouldn’t be magnetic. The stamping process can induce magnetism, but the end rings seem to have a lot. As long as they don’t rust and weld up well, it shouldn’t be a problem.

Only needed one but 2 is always better. The flex pipe inside is very solid and this wil absorb any vibrations and body flex in the exhaust. Easy to weld onto the rest of the exhaust

Nice flex pipes. Short na just built good. The metal is thick not thin. Welds are clean. Just overall built well and a need when building exhaust
