Mach Force XP 304 SS Cat-Back Exhaust System with Split Rear Exit (49-36334-B) by aFe. With Factory Style Exhaust Valve. Exhaust System Type: Cat-Back. Exhaust Tubing Material: 304 SS. Main Tubing Diameter: 3" to 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.

So comfortable and worth the buy
Size: Large, Color: Black
So comfortable!!! There is no seam in the butt and under neath, only in the front but it is really soft and non irritating. I got these for post partum but I’m already wearing them at 8.5 months pregnant. They’re probably my favorite undies right now. The length is also perfect and the material is very soft and stretchy. The waist band is the same, soft and stretchy.

Cotton Blend Was Just Too thick
Size: 3X-Large, Color: Black
I was surprised by how thick these boxers were, thicker than my jeans, much thicker than my PJs! Thick enough that I could wear them outside the home without jeans. In spite of the thickness, they were soft and very comfortable. The 3XL is a perfect fit on my 5’2” apple shaped, short waisted 215 lb body. The boxer cut helped prevent chafing, a major plus. Menstrual pads, with or without wings, do not adhere to this material, a major minus. Ultimately, feeling like I was wearing jeans to bed or wearing two pairs of pants outside the home, was just too uncomfortable for me. So disappointed because these boxers were such a great and comfortable fit.

Comfortable and cool. Does not ride up.
Color: 01-multicolour (4-pack), Size: Medium
Extremely comfortable. Stays cool. Ample coverage. Quality material. They do not creep up. I ordered a medium which I generally take a size small. I have reordered and will reorder again to add more colors to my collection.

Great Value for Cool Thigh Protection
Color: 02-multicolour (4-pack), Size: XX-Large
For the price, I'm not sure there are better women's boxer shortlettes anywhere. I've tried more expensive brands, and for quality and cooling, these are right up there. I have other bamboo viscose undies that still get gross when I get sweaty in the summer, but these, with the large mesh panel, really help wick away a lot of that moisture, keeping you feeling dryer and cooler. I find that the leg openings are comfortable and don't roll up! and the waist band doesn't dig, nor does it roll down. These do not provide any compression, and I wasn't looking for any. I just wanted some cooling, thigh protecting women's boxers that wouldn't break the bank. These are them! Bonus- I've washed them and put them in the dryer (following their instructions), and they haven't shrunk; they look about the same and are nice and soft.
