Large Bore HD 409 SS DPF-Back Exhaust System with Split Side Exit (49-43065-P) by aFe. With Intercooling Tailpipes. Exhaust System Type: DPF-Back. Exhaust Tubing Material: 409 SS. Main Tubing Diameter: 4". Exhaust System Sound: Moderate. Get increased exhaust flow, more horsepower and torque, improved performance and lower exhaust gas temperatures with the aFe Large Bore HD DPF-Back Exhaust System. aFe dyno tests every system for maximum gains, and constructs them from mandrel-bent stainless steel for maximum flow and long-lasting durability.

A performance exhaust system is one of the most common ways of improving a vehicle's operation. The theory is simple; just reduce restriction to increase exhaust flow and you gain power. But all exhaust systems are not created equal; in reality there's more to it than just selling some sewer pipe sized tubes.

aFe tests its systems on the flow bench and the dynamometer to determine the right pipe size. Then they mandrel bend the pipes to ensure they maintain their shape and size throughout the entire length, to provide smooth, unrestricted airflow. Tubes that are not mandrel bent can lose up to 20% of their diameter in sharp bends. A typical aFe system will increase exhaust flow by up to 29% and lower EGT (Exhaust Gas Temperature) by up to 100 , with a corresponding improvement in power and performance.

But performance is only part of the equation. A quality exhaust system should be easy to install and made to last. The pipes of the Large Bore HD system are constructed from durable 409 stainless steel. To ensure a tight seal, slotted and swedged ends are used whenever possible. When used with the supplied premium quality band clamps, the tightest, leak-free seal is the result. Every hanger is thoroughly welded on each side to ensure a strong attachment and the hangers also feature swaged bayonet ends to lock in place once installed. The factory mounting locations are used throughout and a 2-piece tailpipe facilitates adjustment.

Every system comes with clamps, hangers and detailed instructions to guide you through the installation. The Large Bore HD Exhaust System is made in USA.

I like the mildly tart taste of this unflavored, unsweetened drink made up with water.
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I like the mildly tart taste of this unflavored, unsweetened drink made up with water. The texture doesn't bother me, with stirring right from the beginning of adding the water, there is no clumping. After 10 days there is no effect on my bowels which were regular previously anyway. My doctor wanted me to use this although I already have a high fiber diet.

Definitely Not Unflavored. This is Tart / Sour, Which Limits the Options to Certain Juices
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I was expecting an unflavored fiber powder. However, expect a sour/tart taste. This means you can't add it to tea or coffee. I don't think it is appropriate to say that it is "unflavored" as I've had psyllium husk from other vendors that are truly "unflavored" (i.e. no citric acid). Dextrin (another fiber source) is also unflavored. But this Metamucil is tart (like sucking a lime) and can only be added to tart juices like orange juice or lemonade.

Happy it is unflavored
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I was worried about the taste based on some of the reviews. I tried it in my coffee, and I'm glad I did it that way. I keep coffee in the fridge, so that is what I mixed with one tablespoon of this. I use half and half and no sugar. I tasted it. It tastes like burnt coffee. Not a bad thing...thats just what the taste it added. I decided to see what would happen if I added a splash of a flavored creamer. The taste went away instantly. Hope this helps someone!

Effective Daily Fiber Supplement with Noticeable Digestive Benefits
Size: 2.32 Pound (Pack of 1), Style: New
I am very pleased with the Metamucil Premium Blend 4-in-1 Fiber Supplement. Shipping was prompt, and the container arrived well-packaged and sealed securely. There were no issues with leakage or damage, and it was ready to use right away. In terms of product quality, this fiber supplement performs exactly as expected. It’s made with psyllium husk fiber, which is known for supporting digestive health by helping trap and remove waste while promoting regularity. The powder mixes fairly well with water and has a smoother consistency than some other fiber products I’ve used. The orange flavor is mild and easy to drink, especially when mixed thoroughly and consumed right away. I noticed that with consistent use, it helped improve digestion and left me feeling lighter overall. The added benefit of prebiotic fiber support is also a plus, contributing to gut health over time. From a value standpoint, this product offers strong everyday utility. It combines multiple benefits—digestive support, heart health support, and appetite control—into a single supplement, making it more convenient than taking multiple products. Overall, this is a reliable, easy-to-use fiber supplement that delivers consistent results. I would confidently recommend it to anyone looking for a practical way to improve daily fiber intake and support digestive health.

Excellent for Digestive Health and Easy to Incorporate into Daily Routine
Size: 2.32 Pound (Pack of 1), Style: New
I've been using Metamucil Premium Blend for a while now, and it has been a great addition to my daily health regimen. This psyllium fiber powder supplement is particularly effective for improving digestive health. The fact that it's a 4-in-1 fiber supplement is impressive. It not only aids in regularity but also helps with maintaining healthy blood sugar levels, lowering cholesterol, and promoting digestive health. The orange flavor is pleasant, making it easy to drink, and it's great that it's sweetened with Stevia, making it a sugar-free option. I appreciate that this supplement is plant-based. It's a natural way to increase my daily fiber intake, and I've noticed a significant improvement in my digestive regularity since I started using it. The texture of the powder is fine and it mixes well with water, without forming clumps. The packaging is convenient, providing 180 servings, which is excellent for long-term use. It's easy to measure out each serving, and the container keeps the powder fresh. Using Metamucil Premium Blend daily has been a simple yet effective way to enhance my overall digestive health. It's a product I trust and feel good about incorporating into my health routine. For anyone looking to increase their fiber intake for digestive health, Metamucil Premium Blend is a great choice. It's effective, easy to use, and has a pleasant taste. Highly recommended!
