Skunk2 is proud to announce its all-new Alpha Series Header for the ’06-’11 Civic Si. Patterned after our already popular and dyno-proven MegaPower Headers, which have been used by leading, competitive race teams for years, Skunk2’s Alpha Series Header employs many of the same design characteristics and technology. Our decision to produce the Alpha Series Header was driven by our desire to make our race-proven design more affordable and accessible to everyday enthusiasts. New manufacturing techniques allow us to do so at a lower overall cost, making race-winning header technology available to everyone.

Skunk2’s Alpha Series Header for the eighth-generation Civic Si offers Skunk2 performance, industry-leading customer service, and a full warranty policy, all at a price comparable to lesser budget-minded headers. Unlike the budget-minded headers, though, only Skunk2 Alpha Series Headers ensure precise fitment and the peace of mind of knowing that a Skunk2 representative is just a phone call or email away.

All Skunk2 headers are designed and engineered to maximize exhaust flow and increase both horsepower and torque throughout the powerband. The unique design is the result of more than a decade of racing experience coupled with computerized modeling and extensive dyno testing. Each Skunk2 Alpha Series Header features equal-length, sequentially paired, stepped primaries and a 4-2-1 tri-Y design that terminates into a collector with a 2.5-inch outlet. These features, paired with Skunk2’s unique design specs, provide an extremely broad powerband that’s applicable to a wide range of engine sizes and configurations. Alpha Series Headers also feature the smallest possible primary tubes required to achieve optimum overall and peak power. By minimizing the primary tubes’ diameter, Skunk2 is able to maintain the highest possible exhaust gas speed throughout the header, which improves mid-range power and throttle response significantly. Skunk2’s Alpha Series Header provides the perfect combination of top-end power without sacrificing mid-range performance or throttle response.

    Comfortable and Easy to Wear Daily
    Size: 2 Little Kid, Color: Navy/Blue
    My daughter has been wearing these navy/blue shoes since the weather has been less rainy and more sunny. They are great for outdoor play, especially on days when it's warm outside. The knit mesh upper keeps her feet from overheating, and the cushioned insole feels supportive without being stiff. At size 2, the fit is accurate and the width runs a bit roomy, which gave her some growing room without feeling loose. The slip-on design with elastic laces and pull tabs is a real plus. She can get them on and off without any help, which she loves. The shoes are light enough that she barely notices them during long active days. My one small complaint is that the sole feels more like firm foam than rubber, so they can be a little slippery on smooth indoor floors. For the price, these deliver solid everyday value. They look good, hold up well to regular use, and my daughter reaches for them first most mornings. Pros: - Breathable mesh keeps feet cool - Easy slip-on design with elastic laces and pull tabs - Lightweight and comfortable for all-day wear - Accurate sizing with a roomy width - Durable for the price Cons: - Sole can be slippery on hard smooth surfaces - Limited outsole grip compared to rubber-soled shoes

    Great kids' shoe — easy on, comfy all day
    Size: 3 Little Kid, Color: Pink/Lavender
    My kid has been wearing these for a few weeks now and I'm genuinely impressed with how well they've held up. The knit mesh upper keeps feet cool and comfortable during long days at school and outdoor play, and the cushioned EVA midsole does a great job absorbing impact. What really won me over is the slip-on design with elasticated laces and dual pull tabs — my child can put them on and take them off completely independently, which is a huge win. The fit is snug but not tight, and they run a bit roomy in width, which is great for kids with wider feet or those who need a little growing room. At $32, the quality feels solid for the price. Lightweight, breathable, and easy to wear — these check all the boxes for an everyday kids' shoe.

    Cute, Comfortable, Light-Weight Shoes, Perfect for School
    Size: 11 Little Kid, Color: Pink/Lavender, Size: 11 Little Kid, Color: Pink/Lavender
    These have turned out to be great everyday shoes for my 5 year old. She normally wears a size 10, but since that size wasn’t available, I ordered the 11 expecting her to grow into them. I was pleasantly surprised that they already fit her pretty well. There’s still a little extra room in the toe area, but the shoes fit securely around her ankles so they don’t feel loose or slip off while walking or playing. She says they’re very comfortable and loves how easy they are to slip on by herself. The lightweight design is nice for everyday wear, and they’ve held up well so far despite being worn almost daily. They've become her favorite shoes to wear! Also the pink/lavender color is really pretty in person. Overall, I’m very happy with them and would order again.

    Great shoe well made
    Size: 13 Little Kid, Color: Pink/Lavender, Size: 13 Little Kid, Color: Pink/Lavender
    Really good shoes at a fair price. My daughter loves the pink and purple gradient colors. Really beautiful. Shoes have proven themselves very durable. She's been wearing these a few times a week for the last couple months and they still look new aside from some dirt stains. Fit perfectly. Very comfortable. This is always her first pick in the morning when she's getting dressed. Good breathability you can wear these in hot summer weather without sweaty feet. Versatile shoe looks good enough to wear out and about or exercise in.
