Reliability Backed for a lifetime- Armor Plus Series exhaust systems are crafted from corrosion-resistant T409 Stainless Steel - a value-oriented material designed to protect from penetrating rust and will stand up to almost anything you can throw at it. T409 Stainless Steel tubing is easy to clean.

If you're looking for a performance exhaust system with a Lifetime Warranty, this is probably the one for you. If you don't find yourself faced with lots of precipitation and salt, this is all you're ever going to need. All of the tubing is mandrel bent for maximum exhaust flow.

Mandrel bending ensures no rippling in the bends. The end result is that it gives you more fresh air inside your engine's cylinders, allowing it to produce more power and improve vehicle performance and longevity.

It's important to note that T409 Stainless Steel is resistant to penetrating rust but winter conditions, heavy salt air, and road treatments might accelerate the corrosion process, these conditions are not covered by MBRP's manufacturer warranty unless the part or system fails completely. When it comes to a performance exhaust system, choose the MBRP ARMOR PLUS Series for a reliable option backed for a lifetime. MBRP, Stand out from the crowd with a perfromance exhaust system that sounds great.

Great Shoes by Asics
Size: 9.5 X-Wide, Color: Piedmont Grey/Black
Comfortable and durable as heck; classic Asics quality. I love the casual appearance of it, which means I can wear it on a daily basis too. True to the size.

Excellent for a 4E wide foot!
Size: 9 X-Wide, Color: Piedmont Grey/Black
As a female with a wide foot, it is very hard to find a good, comfortable shoe for walking, running and hiking. These were immediately comfortable and really didn't require a break in, although they are more comfortable after a few days of use. My 1st day I put about 5 miles on them and they were great. The cushion isn't like a cloud, but it's there and very responsive. These are very supportive and breathable. I have gone on a few Easy to moderate hikes with them and they're just fine for a dryer trail. They have good grip for rocks as well. 10/10 for these! I will also add that I underpronate, and these provide wonderful stability for that.

Great comfort, but not built for long-term daily use
Size: 9.5 X-Wide, Color: Black/White, Size: 9.5 X-Wide, Color: Black/White
I've had this shoe for almost a year now. I use it almost daily on a walking pad while working from home, plus as a gym shoe. After nearly a year of this routine, I've noticed considerable wear on the sole. Don't get me wrong: the shoe is great and very comfortable, looks decent, and fits great at the start, and has good breathability. However, that comfort has started to fade as the shoe has worn down. Gel-Contends 9 is a really good shoe, but definitely not a long-term, heavy-use shoe. Perfect for casual or rotation use, occasional runs, but don't expect it to last 12+ months of daily wear.
