Overview:

These Flowtech cast iron exhaust manifolds have a 2.25-inch outlet, natural cast finish, and are designed to hug close to the engine block so they fit into a wide variety of replacement and engine-swap applications at a budget-friendly price. Being cast iron means they will provide years of leak-free performance with less under hood noise than traditional headers. Plus, their shorty design means you can route exhaust tubing close to your frame/floor pan for maximum ground clearance.

Features:

  • Intended for GM LS engine swap applications where durability and leak-free sealing is desired at a budget-oriented price
  • 304 stainless steel mating flanges included (mating flange fasteners are not included)
  • 2.25 inch outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold
  • 2 bolt exit flange configuration matches the E-rod exhaust manifolds for a factory like fitment. This allows the use of OE gaskets and fasteners if desired, for an OE quality seal and fitment to emissions devices
  • Cast from Hi-Silicon-Moly Ductile Iron to provide durability and corrosion resistance
  • Tight tuck design provides universal fit for most popular chassis and a clean traditional muscle car appearance
  • Available in plain as-cast finish or with black or silver ceramic coatings for reduced engine compartment temps and improved corrosion resistance

Application:

  • Universal

Good buy
Size: 19inch
Filing it with sand (50 lbs) was a very slow process, but I got it done. The wheels are very convenient for moving the umbrella around, and the wheel locks seems to work well. So far I'm quite satisfied with the base.

Great product
Size: 19inch
Excellent quality! Highly recommend. I love that you can wheel it around to other areas and the wheels lock in place.

Good umbrella stand
Size: 21inch
Works really well. I filled it with water and it works great. The wheels worked great on the pool deck. The umbrella stands upright even in the wind here in Florida. Worth the price. Multiple pole size inserts. 2 pole security screws.

As Advertised
Size: 19inch
The product seems well constructed and rolls easily when wheels are unlocked, even with full weight. Had windy conditions recently and the umbrella was held steady.

Seems like a good product, could use a couple improvements...
Size: 19inch
Product seems fine so far, and the adjustable size for the pole is good. Areas for improvement are a larger fill valve so you could fill sand with something other than a teaspoon. Also would have been better if all four wheels had locks and not just two.
