Large Bore HD 409 SS DPF-Back Exhaust System with Split Rear Exit (49-42045-B) by aFe. Exhaust System Type: DPF-Back. Exhaust Tubing Material: 409 SS. Main Tubing Diameter: 3". 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.

chemical exfoliation is better than scrubbing!
Style: Exfoliating 2% AHA, Size: 60 Count (Pack of 1)
I'm maintaining a professional peel with these bad boys and it's working! I love how they create a smooth surface for make-up. Since I've stopped chemical exfoliation these keep my skin texture looking great.

My Makeup Finally Grips Again, These Pads Work
Style: Exfoliating 2% AHA, Size: 60 Count (Pack of 1), Style: Exfoliating 2% AHA, Size: 60 Count (Pack of 1)
My friend recommended the Thayers toner pads because my makeup was having a hard time gripping on my nose and upper cheeks. She told me I needed at least some basic skin prep, and her routine is a cleanser, these toner pads, a moisturizer, and a weekly exfoliator. She said these pads were great , and honestly, wow. They’re a great value for the price. And I love how it’s travel-ish size for when I am running later. The toner pads alone made a huge difference. My makeup finally started gripping so much better. The first time I used them, my buildup was so bad I had to use two pads, front and back. Ever since then, my skin actually enjoys my weekly (sometimes twice‑weekly) exfoliating pads. This brand and combo make my skin look more youthful, brighter, and clean. It’s such an easy step to add, and I even take them on the go when I’m short on time. Thank you, Thayers.
