Hooker Blackheart now offers stainless steel versions of our popular cast iron lineup of LS swap exhaust manifolds based on the 8502HKR and family. The new stainless steel manifolds offer a number of advantages over the cast iron version, including increased durability, reduced weight, and improved corrosion resistance.

These are available in both natural cast and polished depending on the look you're going for and all hardware is included (gaskets, bolts, and flanges).

- Intended for GM LS engine swap applications where durability, quiet operation, and leak-free sealing is desired
- Polished finish, but also available in natural cast finish for a factory appearance

Great fit, simple style, and comfortable for all-day wear
Style: 7" Swim Trunk, Color: Aqua Blue, Size: Small
These swim trunks are a solid find—comfortable, well-made, and true to size. The 7-inch length is just right: not too long, not too short. They dry fairly quickly and have a mesh lining that’s supportive without being annoying.
The style is simple and classic, and they’ve held up well through swimming, beach trips, and even some light hiking. Great value for the price.
