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

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.

Great Denim jacket!
I purchased a 2xl for my husband and it's a great quality and price. He really loves it. It's a good stretch and he's able to place a hoodie or a thicker shirt and still be comfortable if need be. Will be purchasing him another color of this jeans jacket.

Good Value Denim Jacket With True to Size Fit
Great denim jacket for the price. It feels durable and well made, though the quality is not quite on par with higher end name brands, which is to be expected at this price point. The fit is true to size and matches expectations. It is comfortable out of the box and, like most denim, should become even more comfortable as it breaks in over time. The arm length runs slightly long, but if you usually find sleeves long on jackets, this one will fit similarly.

Great base to add patches to
I've bought this jacket twice now (lost the first one...). Great base for my DIY patch jackets. I buy an XL even though it's a size too large for me. It's a standard denim jacket, not much to write home about. Good pocket size, and I appreciate the functional chest pockets.
