    Hey Guys,

    For those looking to replace the bulky, crack-prone OEM headers, we truly have one of the best options on the market.

    Image Unavailable, Please Login
    Bolt-on upgrade for the failure-prone factory F355 headers. These are lighter, higher flowing, and more durable for increased performance and longevity.

    SOUND:

    Reveal the true exotic exhaust note of your F355. These headers remove the pre-cat in the header which will result in a slightly louder and higher pitched exhaust note. Pair this with the high performance merge collectors and 1-piece mandrel bent primaries used in these headers and you get an exquisitely smooth high pitched exhaust note.

    FEATURES:

    • Fits all Ferrari F355 vehicles (1994-1999)
    • Increases power and throttle response
    • Saves weight versus heavy and more restrictive factory headers
    • High-velocity 4-into-1 merge collectors for maximum performance
    • Constructed from T304L stainless steel with 1-piece CNC mandrel bent primary tubes
    • Designed without pre-cats in the headers for increased flow and performance
    • Includes all required Factory OEM Ferrari Gaskets, Hardware, and Heat Shields
    • Fabspeed High Performance Heat Blankets available for additional protection and heat management - Optional Upgrade Above
    • Simple DIY (Do-It-Yourself) bolt-on installation, no cutting or welding required
    • All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

    What makes you think 4-into-1 headers deliver maximum performance ?
    Do you know what you loose when you switch from 4-into-2-into-1 headers to 4-into-1 headers ??

    We have actually tested a variety of set-ups and dyno'd back-to-back to see which reigns supreme both in power gains and sound.

    There are plenty of options out there, and by no means are our headers the only route for those more inclined to the 4-2-1, but please do know the claim does not come without thorough testing and dozens of hours spent on the dyno/road!

    I have had these on my 355 since 2010 and have over 20,000 miles.

    Chrome plating came off early, so I had them re-coated.

    Better would be if you guys made a set of fitted heat blankets.

    Here is what they looked like when I did my engine out in April and 13 years old:

    Lets start with facts.
    The OEM headers don't have precats.

    You are correct, that bullet was a clerical error. 360/F430' do, 355' do not

    I've always wondered, why don't you add heat shielding similar to the factory manifolds? That I think is the main concern here. I know you have blankets but I can't see them keeping the heat out like full shielding.

    Our proprietary Kevlar/Ceramic Blankets tend to provide more thermal protection than the factory clamshell, given they are relatively decalescent. The clamshell design tends to act more as a sink and can cause excess stress on the manifolds. However, as a few people have mentioned, blankets are a wear-item that needs replacing, similar to rotors/pads once past a certain point.

    In my experience, the protection is also superior to heat wrapping as the wrap tends to trap moisture and cause excess tarnishing. Whereas the blankets allow for some airflow.
