Overview:

99-04 Mustang Long Tube 4.6L 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.

    My Dog Hates It, Yours Might Like It
    Color: Blue goose - pineapple plush
    Material is nice, squeaker is not that great. My dog hates this toy and refuses to interact with it I've tried multiple times to get him to play with it and he'll immediately stop playing if I touch this toy and try to get him to play with it.

    Not worth the purchase
    Color: Blue goose - pineapple plush
    Not for aggressive chewers, my GWP destroyed this in 30 mins. The fins are completely gone and he’s already disinterested. There are better options out there.

    Lovely subtle shine, wonderful scent
    Scent: Sandalwood
    LOVE this shimmer oil. Has a lovely subtle copper/rose gold when used lightly. The shimmer gets more pronounced the more you use, but never obnoxious. The oil absorbs well and fully on damp skin, but I usually use it before going out for the day on dry skin, and it works just as well. The nozzle produces a generous amount with each squirt and has yet to clog or stop up as with some shimmer oils. The oil leaves the skin moisturized and glowy. The shimmer does not rub off easily on clothing and other fabrics. The scent is just amazing. If you have the regular oil, this smells just as amazing. It’s hard to describe…a gorgeous floral smell, but not grandma’s lilly or lavender smell. Just sexy. If sexy and summer, and feminine had a smell, this would be it. Yummy and inherently woman. Get this oil for some shimmer and a splash of confidence.
