Large Bore HD 409 SS DPF-Back Exhaust System with Single Side Exit (49-44040-B) by aFe. Exhaust System Type: DPF-Back. Exhaust Tubing Material: 409 SS. Main Tubing Diameter: 5". 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.

Cute sky blue linen suit for toddler!
Size: 3, Color: Sky Blue, Size: 3, Color: Sky Blue
I got this Trasign Kids Linen Suit in sky blue for my 2 year old, thinking my wife said “blue” (turns out she meant navy or something darker 😅). I actually really like the light, airy sky blue. It’s fresh, summery, and looks adorable on him for photos or special occasions. My wife? Not so much. She immediately said “baby blue ugly” 😅😅 On the plus side: • Soft fabric – linen blend feels gentle and breathable on little skin, no itchiness or stiffness. • Nicely packaged – arrived with very little wrinkling (barely needed steaming), which is a win for linen. • Good fit for a toddler – true to size, easy to button, and the shorts/pants have adjustable waist for growing kids. • Looks sharp once on – the set gives that classic little gentleman vibe without feeling over the top. It’s a quality piece overall, just a classic case of “what one spouse loves, the other doesn’t” on the color. If sky blue works for your family (or you’re shopping solo like me 🤣), it’s a solid buy.

Sharp and goes well with fancy, or jeans. Looks great for the price.
Size: Large, Color: Black
As tweed Herringbone vests go, this is rather nice and fits well. I'm 5'10", medium build and the Large fit nicely. I ordered it to go with my Oktoberfest Lederhosen outfit (worn to Oktoberfest in Munich), and it worked well. It'll also work with jeans. It's not some high quality piece, but for the price, appears more expensive than what it costs.

Nice Qualtiy for the Money
Size: Large, Color: Light Blue
I originally ordered this vest in XL based on other reviewers' suggestions to up size, but I returned it for a large. Vests should fit snugly and not be loose. I'm 5"9" and 175lbs and the large was a good fit for me. The material is not as heavy as I expected based on the photos but it is not flimsy. It is well constructed with a nice liner. For the money it is a really nice item. I have nicer vests but then they cost several times what this one did. Overall, I am very happy with it.
