>Designed for racing, track events and off-road use, Fabspeed's Long Tube Competition Race Headers with integral Side Muffler Bypass Pipes are designed to maximize the horsepower and torque bolt-on potential of the Porsche 991 GT3 / GT3 RS / 911 R engine by increasing exhaust flow from the engine cylinders straight into the exhaust system. This system was designed, incrementally dyno developed and maximizes engine power all throughout the powerband.When the first 991 GT3s landed on North American soil, our engineering team immediately got to work and developed a Race Header to maximize the performance of the track weapon. Our original medium tube modular header design was very successful, but we were looking for more power. Consequently, we were approached to enhance a GT3 RS and welcomed the opportunity to refine our long tube header design further. After extensive development, including dyno and track testing of various designs, we’ve uncovered the correct formula to unlock the maximum performance and exhaust flow from the Porsche 991 GT3 / GT3 RS / 911 R. There is no better designed and engineered race header system for the Porsche 991 GT3 / GT3 RS / 911 R available worldwide. The Fabspeed Motorsport GT3 header was developed in conjunction with the racing engineers at Burns Stainless LLC Costa Mesa California. Burns Stainless is a World leader and innovator in stainless steel header design, testing and building high velocity merge collectors.

Modern luxury with summer fabric that performs above its price!
Color: Beige, Size: 14, Color: Beige, Size: 14
Wow! My son wore it for Easter Sunday and this suit fits the bill! The linen material is spot on--not too heavy and not too light especially since the weather is warming up now. The jacket is quality made--the design is modern executive, the stitches are strong no flaws to note. The pants are tad bit longer but that's okay, build quality is also great. The white shirt is decent and matches well with the rest of the set. The bow tie and tie itself is a great complimentary to the set, though optional to wear. The whole set just has that quality you would really look for in the price range you would want to pay. Overall, best value for for the, wear right outside the bag, maybe a light ironing otherwise it's perfect! I highly recommend it, no complaints here very happy with this suit!

Heavy linen character, but a beautifully tailored suit!
Color: Beige, Size: 4, Color: Beige, Size: 4
This is a really nice linen suit! The jacket is beautifully made and well-tailored, with a fun speckled texture that has lots of pretty color variation (we ordered the beige). When I placed it side by side with a similar linen suit from another brand, the difference in the linen texture was really noticeable — this had a much stronger linen character that stands out!
It has three useful pockets on the outside of the jacket, which is great for little hands. The only downside is that one of the inside pockets is just for show (faux), which was a bit surprising and somewhat disappointing for my little guy.
The pants have pockets too, but they aren’t very deep — perfect for small treasures, but not much more. The pants are made from a lighter, thinner single-layer linen compared to the fully lined, double-layer jacket, which makes sense for comfort and easy movement.
The pants didn’t come with a front crease ironed in, so you’ll want to press one yourself. The linen did pick up some creases from being folded in the package, but it doesn’t seem quite as wrinkly as some other linen fabrics I’ve tried. Still, like most linen clothes, especially for boys, the pants will need occasional ironing to keep them looking neat and crisp, especially after a day of play and general wear. The structured, lined jacket stays looking smoother and more put-together with less effort.
It also came with a bow tie, a neck tie, and a tuxedo-style white shirt as extras. The ties aren’t great quality — they’d work fine for quick photos but probably won’t hold up to much actual wear. The formal white shirt feels a bit funny paired with the casual linen suit, but I don’t mind at all. We already have white shirts that we prefer, so we’ll use those instead. For us, the extras are really just bonus items we won’t plan on using.
Overall, it’s a handsome little suit that’s perfect for special occasions like weddings, family photos, or holiday events. My kid looked adorable in it! The stronger linen texture on the jacket gives it a premium feel that I really like. Just be ready for a bit of extra care with the pants to keep everything sharp.

Great suit set
Color: Light Grey, Size: 4
It is incredibly attractive and includes everything a young child needs for a special occasion.
The material is a 75% polyester and 25% linen blend, and the outer fabric feels remarkably smooth. Its unstructured design allows for an attractive, natural drape, and the blend conveniently allows for machine washing at home.
As is typical with linen-based materials, the fabric can be naturally stiff and prone to wrinkling, so I recommend ironing or steaming it before use. The lightweight feel makes it an excellent choice for the spring, summer, and fall months.
Overall, this suit offers exceptional value for the price.

Perfect fit and great quality for the price
This suit was perfect for my son. The fit was exactly as expected. The quality is excellent for the price—it feels well made and durable enough to last through multiple wears. It doesn’t feel cheap or flimsy at all.
It also looks really good on him. Clean, polished, and great for formal events like weddings or parties.
Overall, a fantastic value with great quality and a great fit.
