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.

  • Oversized exhaust ports

    Loves this wallet
    Color: Coffee6227, Material Type: Leather
    Bought this wallet for my husband and he loves it. It’s softness, design, ease of use, perfect size and great value for the money. The magnet strength is perfect. Bought for Christmas and he’s still telling me how wonderful it is. Great product .

    Quality Meets Functionality
    Color: Black8017, Material Type: Leather
    Very impressed with the quality material and functionality of this wallet, I had to buy a second one. (Coffee + Black). It opens and folds-out like a breeze in your hand and stays closed when not in use. The pop-up card holder mechanism works well too. The overall compact size makes up for the thickness of this wallet. It is thick. I wouldn’t recommend sitting on this one, but it’s small enough to keep in a front pocket while seated.

    Nice wallet but...
    Color: Tiger Eye8018, Material Type: Leather, Color: Tiger Eye8018, Material Type: Leather
    I've been using this Bulliant wallet for a few weeks now, and it's been a solid upgrade from my old one I carried. I like the design of the wallet. It is sleek and clean looking. It hold a good number of cards without feeling bulky. When I first loaded the wallet up, the card slot was a little tight but that is to be expected. As far as durability goes, the wallet holds up. It isn't made of cheap material. It protects my cards and keeps everything organized. The only downside I would say is if you wear your wallet in your back pocket it is going to be a little bulky. Also if you have a lot of cards like me, you will run out of room and have to decide which cards to carry. But overall a good wallet that I would purchase again.
