Mach Force XP 409 SS Cat-Back Exhaust System with Single Side Exit (49-46021-B) by aFe. Exhaust System Type: Cat-Back. Exhaust Tubing Material: 409 SS. Main Tubing Diameter: 2.5". Exhaust System Sound: Aggressive / Loud. Get increased exhaust flow, more horsepower and torque, improved performance and lower exhaust gas temperatures with the aFe Mach Force XP 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. This system begins at the Cat (Catalytic Converter).

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. Some systems also include a straight muffler delete pipe if a more aggressive sound and maximum flow is desired. 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 muffler and all pipes of the Mach Force XP 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.

aFe (Advanced Flow Engineering, Inc.) manufactures performance products for late model cars, light trucks and SUVs. The company was founded in 1999 with an initial concentration on high performance air filters. Since then, the company product line has broadened to include cold air intakes, fluid filters, exhaust systems, intake manifolds, intercoolers, programmers, differential covers, transmission pans and throttle body spacers. The team of engineers, machinists, production and sales people at aFe have many years of experience in their respective positions, and together work to ensure they produce the best automotive products on the market.

The right length
Size: 30-Foot, Style: Standard End
Well made and heavy duty. It is an odd length but that’s what I wanted and needed. 50 ft. Too long and 20ft. Just not long enough . 30ft. Gives me the length that I can use and not have to try and stretch it and gives me a bit of slack and no tension in the run.

Works awesome for continuous 40 amp loads while charging an electric vehicle
Size: 30-Foot, Style: Standard End
I took this extension cord on a nearly 6,000 mile road trip in my 2015 Tesla Model S 85D and this extension cord enabled me to easily reach 240 volt outlets at the 4 friends/families homes we stayed at to charge our car overnight. I used NEMA 10-30 and 14-30 adapters on the end to be able charge from dryer outlets, and just used the extension cord as is to charge from NEMA 14-50 outlets. It is heavy and bulky, but it fits easily into the frunk and we could fit many other things still in the frunk with it. Totally worth buying and having to greatly expand the charging possibilities. This 30 foot cord along with the gen 1 mobile connector the Tesla came with which is 20 feet long means we can reach outlets up to 50 feet away! We've never needed that, but we have parked out in the driveway of the home before and this cord enables us to reach through the garage and into the laundry room of the home. The biggest inconvenience is that the cord is real thick and it forces any doorways to remain open by an inch while charging but that's not the cord's fault. As far as extension cords go this cord is quite expensive, but considering how heavy duty it is I think the price is worth it. I was never able to charge at the full 40 amps this cord is capable of due to the circuits I was plugging into all being 30 amps. Charging at 24 amps overnight and this cord was still cold, but that's not saying much.

Great Cord and Great Price
Size: 30-Foot, Style: Standard End
I got an email from Camping World telling me about a sale on these extension cords. I looked at their site and they wanted about $140. I really needed the cord and almost ordered from them, but I checked Amazon first. Surprise: It was lots cheaper here. Yay. Deal done. This is a great cord. My stock 50A power cord that came with my fifth wheel is too short to reach to my house and plug in and charge my coach batteries. I've used other extension cords, but they sometimes get hot--especially if I don't completely uncoil them. So now I use this Camco extension to reach the outlet in my garage. Even though the garage outlet is only a 20A breaker, it's still a more efficient charge and safer connection to use the stock cord, plus this extension, plus the dog-bone adapter to reduce down to the 110 outlet. The connections are clean and I get the best charge I can possibly get from that outlet. As long as I don't run the air conditioner or any other heavy appliances, I won't trip the breaker in the house panel. This cord is constructed well. The ends are good and easy to plug/unplug. The Velcro carrying handle is a big help too. Well done.

Honestly. Hope for the best, will update...
Size: 15-Foot, Style: Standard End
Durable solid high quality built. Got a 15 ft and the length is perfect. It's so heavy, can't imaging if I have got a 25ft or 50ft one. I bought it because of its using 6 gauge wires, and 8 gauge for the ground. I am using it on a 40a circuit breaker and running on a 8 gauge wire from the breaker to the NEMA outlet, so limited it to charging the EV with 32a max. Not expecting it to be heating up the wires or burning the heads, will update this posting if it does. May 20, 2025 update: solid build cord, very durable. It does a perfect job what I have expected. The head feels just slightly warm with my setup. Glad that I bought this.
