Overview:

65-73 Mustang Long Tube 260-302 Raw 409

JBA long tube headers are the number one choice for maximum performance gains and high RPM efficiency. Available in 409 or 304 Series Stainless Steel.

All JBA long tube headers feature large mandrel-bent stainless steel primary tubes, oversized exhaust ports, extra thick 3/8 one-piece flanges, and proprietary JBA Firecone® merged collectors for smooth flow. Each system is designed to give the maximum amount of ground clearance possible, so lowered cars do not drag the collectors.

    A great, comfortable pillow!
    I bought a couple for myself recently and now I am buying two for my daughter, but having them shipped by Amazon. She’s having surgery soon and I want her to have a very nice pillow at home while recuperating.

    Not for me
    If you like super soft pillows that you spend 30 something bucks on and feels like your head goes straight to the mattress this is the one for you. They can are soft enough to ball up like the old flattened pillows they're meant to replace. They don't feel comfortable to me.

    Wonderful
    Size: Cooling Queen, Size: Cooling Queen
    I absolutely love these pillows From the very first night, I could feel the difference. They are incredibly comfortable, soft, and still provide great support for my neck and head. Plus, the modern design makes my bed look so much cleaner and more elegant. The fabric feels high quality, and the pillows keep their shape really well. I genuinely feel like I’m sleeping better since I started using them. Great value for the price, and I would definitely buy them again. Highly recommend
