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

Our dogs hurt their mouths chewing these bones
Color: Purple & Blue
I don't do a lot of reviews because I realize many are objective opinions. However, in this case I felt it was necessary to warn others. Our dogs are aggressive chewers. Their last rubber bones (not these) which we've purchased before, and recently purchased again, were destroyed quickly. Chunks of rubber came off the ends. Since those didn't hold up like they used to, I found these harder bones hoping they would last longer. They were able to gnaw into the hard plastic within a few minutes. This created sharp edges that cut their mouths. When I saw a bit of blood on the bones, I took them away from the dogs and threw them away. I wondered why they quit chewing on them after being so excited at first. Also, these are hard enough to damage a tooth.

Pups have shown zero interest in these toys….
Color: Purple & Blue
I would agree that these are indestructible being neither of my dogs have shown any interest in these at all. At this rate they should last forever…

Durable but losses interest
Color: Purple & Blue
My dog is an aggressive chewer. She was interested in this toy while it was new, but soon after lost interest. Good news is although it took a beating it did not break or splinter. If soppy toys are disposable in your house, give it a try.
