Large Bore HD 409 SS DPF-Back Exhaust System with Single Side Exit (49-42039-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.

Good Deal
Price is right, no stuffing to pick up, dogs love them and just throw them out after they’re dirty and your dog got the squeaker out.

Best Tennis Balls Ever
Color: Non-Squeaky - Pack of 12, Size: Medium
Admittedly, I haven't had these for very long, received on Jan 7 and today is Jan 19., 2021, only 12 days. But, we have a terrier mix who hasn't found a tennis ball she couldn't destroy given an hour or two. That is until now. Twelve Days later? She hasn't managed to destroy it at all. We have a puzzle cub that came with a ball inside it. It only took her a couple hours for the ball to rupture at the seam and another 10 minutes to completely destroy it beyond recognition. We put one of these balls in there and here we are over a week later. Not only has she not destroyed the ball but she hasn't been able to get this one out. She looks so silly trying to carry the ball inside the cube. It's hilarious. Anyway, I digress. I would totally recommend this toy for an yone who has a dog that lives to play fetch bit keeps destroying the balls. By the way, Update: Jan 31, 2021 and still going strong. No signs of damage.

Perfect tennis ball size.
Color: Non-Squeaky - Pack of 12, Size: Medium
Like most doggy balls they dont last as long as real tennis ball, but a real tennis ball can wear down her teeth. Great colors, tho in a few days they are yard colored cuz of the slobber and nature on it. Love the handy mesh bag for keeping put away until we need to get out a new one. My dog loves the no squeaky. To her squeaky is inside toy and too distracting for outdoor play. She really enjoys fetching this ball.
