Large Bore HD 409 SS DPF-Back Exhaust System with Single Rear Exit (49-13028) by aFe. Exhaust System Type: DPF-Back. Exhaust Tubing Material: 409 SS. Main Tubing Diameter: 4". Exhaust System Sound: Aggressive / Loud. 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.

Very Sturdy Industrial Shelves with a High-End Look
Size: 48in, Color: 3-layer
The OLDRAINBOW Industrial Pipe Shelves with Wood Planks 3 Tier 48in are very sturdy and have a high-end look once installed. The combination of metal pipes and wood planks gives them a strong, rustic-industrial style that looks more expensive than expected. They feel solid and well-built, not flimsy at all. Once mounted, the shelves feel very stable and can hold a good amount of weight, which makes them practical for books, decor, or kitchen items. Overall, these shelves are both functional and visually impressive. They add a polished, high-end feel to the space and I am very happy with them.

Really sturdy. Beautiful addition in Kitchen
Size: 36in, Color: 3-layer
We put this up in our kitchen to hold our recipe books and other odds and ends. It is really beautiful and ties the space together nicely with the blank wall we had. It’s sturdy to hold several recipe books and a great price point for the quality. The only thing was that the second shelf did not line up from one pipe to the other. The top and bottom shelves aligned perfectly, so the pipes were leveled, but it seems that the pipes in the middle were not equal distance and the shelf wobbles. We’ll be putting something underneath one end to balance it out.

Very easy to put up and assemble!
Size: 48 inch 3 Tier, Size: 48 inch 3 Tier
We were looking for a nice shelf over our coffee bar, and this industrial pipe shelf was perfect! This was very easy to assemble! Simply put in your anchors and screw in the bases! We ordered the three tier shelf but only needed two, and it was very easy to make that adjustment! I loved that this was solid wood shelving rather than particle board.
