Flowtech headers are designed to provide optimum exhaust flow for increased horsepower, torque, fuel economy, and improved throttle response. Leak-tested for maximum performance, they feature the industry's best welds for durability and are carefully engineered for precise fit. Available for an wide range of applications, they are offered in block hugger, competition, fenderwell, lakester, long tube, mid-length, shorty, upright, and turbo styles. Varying with the application, Flowtech headers are constructed from sturdy and lightweight cold-rolled mild steel or stainless steel for increased strength and durability. All tubing is mandrel-bent to provide consistent tubing diameter for smooth flow and increased exhaust velocity. Extra-thick, machined header flanges provide a leak-free seal and maximum strength. For long-term rust and corrosion-resistance, available finishes include natural and polished stainless steel, high heat-resistant black paint, or a satin silver metallic ceramic thermal barrier coating. All mounting hardware and premium gaskets are included.Depending on application, features may include: Shorty-style headers will work with catalytic converter equipped vehicles; head pipe fabrication may be required Leakproof O-ringed port seals on select headers Available to work with factory power steering and power brakes Where applicable, welded-in collector merge spears control exhaust gas re-entry into primary tubesImportant notes: Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Ceramic coated headers require several heat cycles to fully cure before they will withstand extreme heat. Hooker recommends using cast iron exhaust manifolds or old headers to break in new engines to avoid coating damage. Flowtech does not recommend the use of header wraps as this will void the warranty.

Great toys for aggressive chewers
Size: Medium/Large, Color: Turkey Day Drumstick - Large
These are great toys they last a while they are destroyed after a while but both dogs are aggressive chewers but they last about a year and a half. And they are go to toys they have one that is a shark mouth and they love it I have bought 4. (two of them the pups lost ).

Durable and Fun, Just Gets a Bit Rough
Size: Medium/Large, Color: Chopper - Large
This is a really good toy overall, especially if you have dogs that love to chew. My dogs were immediately into it—they play with it nonstop, toss it around, and stay entertained for a while, which I love. It definitely holds up better than most toys we’ve tried.
The only reason I’m giving it 4 stars instead of 5 is because over time it does start to fray a bit and gets a little rough, especially with heavy chewing. It’s not completely indestructible, but it still lasts longer than a lot of other toys.
Overall, still a great buy and I would recommend it if your dogs need something tough but fun!

Worthwhile!
Size: Medium/Large, Color: Turkey Day Drumstick - Large
I have a small dog with a really strong bite! Usually have to buy toys that are meant for bigger dogs. This has lasted us for what feels like forever. It does sound very heavy when dropped! My dog loves it though! Would definitely recommend!

Ohhh Mr. Iguana
Size: Medium/Large, Color: Illana the Iguana - Large
Mr. Iguana is a house favorite! I got my first one of these in a barkbox and my dog loved it so much, i went on the hunt for another one. Amazon saved the day! I own about 7 of these now. They are prefect for dogs just love to chew, they hold up great! And they are heavy duty, super easy to clean! My dogs are very happy, great value for the money! Doesn't have a smell, vibrant colors! Noise level is quiet, minus my dogs chewing !

Not for strong chewers
Size: Medium/Large, Color: Dog Ness Monster - Large
Initially, I really liked this for my dog. She is about 8 months old and still loves to chew and destroys most toys in a few minutes. When we got this, it seemed like it would hold up for a while despite being clearly gnawed on. Unfortunately, once she focused on the softer "water" portion of the toy, that is where things went downhill with this toy. After a few short chew sessions, she was tearing chunks out of it. We had purchased a replacement since she liked the original so much, and after about 5 minutes with the replacement, she had taken enough out of the blue section that we immediately threw that one out as well. Overall while the green portion held up, the blue didn't. I can't recommend this for strong chewers.
