Alpha R35 GT-R 90mm Catted Midpipe

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.

Pocket and ability to hook my speaker to
Size: 32, Color: Black, Size: 32, Color: Black
I can't believe how comfortable they are and I'm very happy with all the pockets in the shorts. I bought the black as it my favorite color but will definitely be ordering all the colors available as they can be used as dress shorts.

Great shorts
Size: 34, Color: A-army Green
Ideal for everyday wear. I got 3 pairs before even trying them & I must say, they are really good. The pocket zippers get caught every now & then, but easy enough to correct. They look decent, easy wash & dry quickly, comfortable, plenty of pockets. Great buy for the price.

Great Shorts! bad zippers.
Size: 36, Color: A-dark Grey
1st off these are basically swim trunks. I like the design of the shorts and the appearance, they are very lightweight and quick drying and overall serve all of MY purposes. If you're buying them for secure front pockets that close with the zippers just don't buy them. The zippers on the front "cargo" spot of the shorts broke on the second wearing. If you have nothing better to do than try to fix them by all means they can be fixed short term and then eventually they just separate again. The pockets work fine (they are ALL mesh lined pockets) for just putting stuff in them but securing them (at least in the case of the pair i am wearing right now) isn't an option with the zippers. That said the fly itself hasn't failed me. The back pockets have ONE velcro closure on the inside so you can reach into them easily without two velcro closures to fight with which i think is a good design.

Size: 36, Color: A-dark Grey
I had to return ( and re order ) because the sizing as most with these non american sizes got me like man others. Fitment was not bad, they are a bit longer than I prefer, however the issue I had was not there. I ordered an xl I believe and the size I got was a 36, a 34 would have likly been a better fit and will try that on my re order. As far as the material goes, they are thin, they are light, and you could use these for anything that has to do with water, even possibly swimming. The design is not bad, they do not feel like something that you would want to be to aggressive in ie. work environment where cuts are prone as these would offer no protection at all. As the sellers title says, ( Outdoor hiking, quick dry, travel cargo shorts, golf fishing etc. ) Leave out the whole tactical thought here. These are not tactical, they do not even need to be considered tactical at all. For those like me who are trying to find a cheaper alternative to expensive clothing for work, etc... these fit the bill, just need to figure out your proper sizing. I normally wear a 34 in pants and shorts which gives me a little room for my concealed carry, and 32 when Im not carrying. So the size 36 that I got would not be a valid option, but the 34 would / should be a more true fit. The material, to me, it felt like and sounded like a light wind suit or windbreaker jacket.. just to give you some sort of comparison.
