Large Bore HD 409 SS Cat-Back Exhaust System with Single Side Exit (49-44002) by aFe. With Muffler Delete Pipe. Exhaust System Type: Cat-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 Cat-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 and muffler construction. 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. An 8" diameter by 30" length, straight, flow-through, perforated muffler is included in the system. A straight muffler delete pipe is also included if a more aggressive sound and maximum flow is desired. This 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 muffler and all 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.

Top of bag very narrow
Color: Reddish Brown
Why they would sew the top of this bag making it so narrow to get into or see your stuff is difficult for me to understand. Love the bag, hate they did this. Such a shame, I would have loved to keep this bag as it was the perfect size and the leather was nice. Bummer

This is a gorgeous pocketbook. You will enjoy it.
I absolutely love this pocketbook. It’s roomy enough for everything. I know some people said you could put a laptop in it. I do not see that really happen unless it’s something very small. The stitching on the sides of it prevent it from opening very wide, I love the color of the leather. I think it’s beautiful for the fall and winter months. I would definitely buy it again. I feel it’s a good value for the money.
