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

Don’t buy it
Color: Red/Battery
Stoped working after 6 months. I wish I had purchased the same one I had, Kitchen Mama, but the price was better for Circle Joy. Silly me I won’t be fooled again. I have arthritis and can’t use manual openers. This is going in the trash today. Btw- I only use it 1 or 2 times a week.

Excellent can opener.
Color: Red/Battery
Love it! Works like a charm. I have arthritis which made opening cans with the type I’d used for years very hard. I didn’t want one on the counter, this fits perfectly in a drawer. I know a couple our friends have ordered one.

Worth the Money
Color: Red/Battery
I bought this thinking, "Will it really work the way it shows?". The answer is yes. Put it on the can, press the button, and then it does its thing hands off. It does leave a smooth edge too. Not too speedy, but better than having to fight with your manual to get it to catch the edge.

Great upgrade compared to others
Color: Rechargeable with Storage Stand and Box - Black
This frother is far superior to other hand held versions we’ve owned. The attachments are much sturdier and don’t bend as easily (which made the others we’ve purchased quite useless). Rechargeable battery seems to last longer and provides plenty of power even on the lowest setting. The little wisk easily whips up eggs for a morning omelette and frothing cream and mixing powder into drinks are super easy with the other attachments. Finally, the stand is actually sturdy and balanced enough that it doesn’t easily tip over.
