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.

    My new edger
    Style: 9" 2T Cutting Blade
    I love this edger, I attached it to a Kobalt 24V trimmer with detachable head. It took me a minute to remember how to use an edger with a steel blade after I have been using a string edger for the last five years. The weight is liter than the battery/motor pack. The design and functionality is amazing, I love the adjustability of the depth control system. This thing is super easy to use, loosened one bolt, slide on the attachment align the silver push button and tighten the one bolt by hand and go to work. The durability is yet to be determined, it well made. I like that the right side is open faced which means less chance of clogging up the blade. I am very happy with this purchase and I believe it is a great value for the money

    Made it through the first season
    Style: 9" 2T Cutting Blade
    Product value compared to name brands not to bad so for. Not sure I'd use it for contract work, but great for homeowner use. Engine seems to have an odd burning smell, but performs good (yes I have the correct oil/gas mix ratio which is 50:1). This is very similar to the Stihl models, aluminum shaft tubing on the attachments appear to be slightly thinner than Stihl, but they perform fine. So far it's been a great value for all the attachments you get in the kit. Definitely like the angle capability of the hedge trimmer and ease of changing out the attachments. Chain saw blade did dull fairly quick, but expected that based on it's size. Jury still out on longevity.

    Edger Does Not Fit The 52CC Trimmer
    Style: 9" 2T Cutting Blade
    Might be a great cutter head?? I purchased the 52cc trimmer and edger as a package, however the edger does not fit the trimmer??? Therefore, it is useless... Will see if it fits my 25cc trimmer and maybe change the review... They should tell people in the description that their edger will not work with the 52cc trimmer....
