Large Bore HD 409 SS DPF-Back Exhaust System with Split Side Exit (49-44043-P) by aFe. Single To Dual Exhaust Conversion. 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.

Great Addition!
Color: Black
Why did you pick this product vs others?: I just started a powdered drink routine recently and was having a difficult time mixing it with water. I would consistently end up with small nuggets of mix making it unenjoyable to drink. I knew I needed a mixer and was glad I found this device when I did. It works perfectly! I like the fact that it comes with its own stand and included two mixing heads. It is solid, well-designed, and you can feel the quality when you pick it up. The variable speed of the mixer is perfect for ensuring that everything is blended well. I haven’t used it to “froth” anything yet, at least not on purpose, but I accidentally found out that it can do that well. This is a great addition to our kitchen and is very easy to wash after use. So far…no issues. Highly recommend for those of you looking for the right tool to make sure those protein mixes aren’t full of unmixed nuggets.

Low foam
Color: Black
Love this frother. It is great quality and the turn speed is amazing. My only issue is this. It comes w 2 wands and they are both singles. The single is great for stirring things up. It does not make a lot of froth and for some things it’s perfect but sometimes I like a lot of froth and I wish it either came w a single and a double or you could purchase a double separately to intermix. I don’t want to buy a whole other unit just for the double. I wrote to them bc the double frother they sell doesn’t look as good as this one but sometimes a girl needs a lot of foam and sometimes th stirring is perfect.

Powerful!
Color: Lux Galaxy, Size: Rechargeable Z1 Motor Max
This thing is powerful and works great! I was hesitant about some of the negative reviews, but this is worth it so far. I use it every day and haven't charged it in the week that I've had it. Some people complained about turning it off.... It's not that hard. Just hold the button down for a second or two and it shuts off, no fuss. If you tap/press the button you'll cycle through the next speed and then off. I only use the first speed to make my protein shake and matcha. I feel like the high speed would just whip everything to pure foam! I'm hoping this lasts me a long time.
