The Alpha R35 GT-R 90mm Catted Midpipe is one of the largest midpipes available on the market. Where most systems implement two 76mm (3”) pipes that merge into a single 76mm (3”) primary pipe, we offer a larger 90mm (3.5”) primary pipe to optimize exhaust gas flow. This reduces turbulence and unwanted back pressure – freeing up horsepower and improving turbo response.

Remain Compliant With No Loss Of Horsepower

So that your R35 GT-R remains compliant with state and local emissions regulations, our midpipe incorporates a set of high flow catalytic converters that are EPA certified in 49 states. These GESI Ultra High Output (UHO) stainless steel cats provide the highest level of emissions control with no notable loss in horsepower when compared to a cat-less midpipe.

With an Alpha 90mm Catted Midpipe installed, your GT-R will maintain the power of a straight pipe setup without the hassle of having to switch back to your stock midpipe in the event you are called for emissions testing. Our cats are designed with racing in mind and can handle the most severe of driving conditions. Unlike standard cores used by many of our competitors, these will withstand up to 1500 degrees F and will not rattle loose after repeated heat cycles and heavy driving.

Superior Construction. No Compromises

Like all products we manufacture, the Alpha R35 GT-R 90mm Catted Midpipe offers you unrivaled fit, finish and performance. Each piece is constructed of high quality stainless steel and hand TIG welded by one of our AMS master fabricators. In addition to a superior set of catalytic converters, we also use the highest quality stainless steel flex sections and 3/8” thick connecting flanges to complete an overall design that will last the lifetime of your GT-R.

arm holes too large, shirt too long, size down
Size: Small, Color: Wine
I am 110 pounds and 5’2”. I ordered a small. The fabric feels awesome. The neck area and straps are perfect. However, the arm holes are quite large. The bottom of the arm hole isn’t straight down, flush with the shirt. It angels outward. If you lift your arms up it looks odd. I should have ordered an extra small. But even if I do that, I still think the arm hole will look odd. I will likely return this or wear it at night or at the gym with yoga pants. The shirt is a tad bit long. If you wear short shorts, the shirt would cover your shorts.

WELL CONSTRUCTED. GOOD STITCHING ON NECKLINE AND SLEEVES. GOOD FOR TALL PERSON.
Size: X-Large, Color: Orange
The Automet women's loose-fit tank top is sized just right for me. I'm 5'11', 200 lbs., 57 years old. I've got some back fat that would be obvious in a tight top. This tank is loose enough to hide my back fat but not too loose. From the front, it does not appear loose at all. It's the back area that has extra room. It has a nice, scooped hem. One special feature is the double stitching on the neck and shoulders. It is well-made. It looks more expensive than it is. I bought the Automet tank top in the color orange. It is NOT see-through, nor is it thick. I live in Arizona, in the desert part, where it gets hot. This tank is thin enough to keep me comfortable from May to October when the heat hits. It's hard for me to find the "perfect" tank. I've tried so many. I feel you would be wise to give this tank a try. Worst case, you return it. I love the orange one so much, I plan to purchase all the colors for this hot summer coming up. I wish all of you the same happiness I have found with the Automet tank top.

The perfect throw-on athletic dress (with built-in shorts!)
Size: Small, Color: Navy Blue
I’ve been loving this athletic dress—it’s one of those pieces that’s both functional and cute, which is hard to find. The fabric is lightweight, breathable, and slightly stretchy, so it’s comfortable whether you’re running errands, going for a walk, or just chasing kids around all day. The built-in shorts are a huge plus. They stay in place well and make it feel more secure than a regular dress, especially on busy days. I also appreciate the pockets—they’re actually usable and don’t feel bulky. The fit is relaxed and flowy, which I personally like because it’s easy and flattering without clinging. The straps are adjustable, so you can customize the fit a bit depending on your height or preference. I’d say it runs true to size for a looser fit. If you want it more fitted, you could size down, but I like the casual, sporty look as is. Overall, this is a great everyday summer staple—super easy to style with sneakers or sandals, and perfect for travel or on-the-go days. I’ll definitely be getting more colors!
