Flowtech headers are the perfect combination of performance and value. Flowtech long tube headers are precision engineered using mandrel bent tubing, formed collectors and 5/16" flanges with sealing rings for a leak-free seal. All mounting hardware and gaskets are included for a simple installation. This header is coated in a high heat resistant black paint for a stealthy appearance.
Features:
- Mandrel-Formed Power Plenum
- Leak Test For Max Performance
- Fuel Economy From The Engine
- Constructed of .049 cold roll flash mild steel tubing
- Include All Mounting Hardware
- Leakproof O-Ringed Port Seals
- Precision engineered for fit, performance and economy
Fitment Notes:
- Will not fit with A.I.R. injection pump.
- It may be necessary to raise the automotive column cross shaft linkage by rotating the mounting brackets on the frame and transmission 180º
- Will not fit vehicles with power steering.
- 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. Flowtech recommends using cast iron exhaust manifolds or old headers to break in new engines to avoid coating damage.
- The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Flowtech does not recommend the use of header wraps as this will void the warranty.

Not indestructible, but well worth it
Color: GT-2P, Color: GT-2P
First things first…it’s solid, literally. Very hard and if you have tile or wood floors, it’s ridiculously loins when it hits the floor. With that said, we’ve had our dogs chewing on these for about a month now. All 3 are aggressive chewers. As you can see in my pic, there are signs of chewing on the ends of the bone. I’ve noticed they all seem to gravitate towards them assuming they think they can chew through it. Not the case. The material itself made of is hard but I almost think they enjoy the feeling of the bone against their teeth and gums. I regularly watch our biggest chewer lay on the couch for what seems like hours just biting on it. The bone itself has held up extremely well and haven’t shown any signs of splintering, breaking, or falling apart. This making us feel the bone is safe considering how much they love to chew and how well it’s held up. It looks like a bone. This seems to be a factor in them wanting and/or seeking it out when they want to chew on something. Great to keep close in the living room and gets almost immediate engagement from all of them when I pull it out. Well worth it if you have problem dogs that chew everything and anything. Great as a distraction and from what we’ve seen, great for hours of engagement. Highly recommend for sure.

Excellent toy for aggressive chewer dogs!!!
Color: GT-2P, Color: GT-2P
These treats are super heavy duty! My German shepherd is a good eater. This includes chewing on many things that are not make to be dog toys. I need to keep her occupied and chewing toys that are made specifically for aggressive chewers. She’s quite wily and can usually take apart those supposed aggressive chewers toys very fast. That’s why I love these toys. They actually are for aggressive chewers and keep my best friend busy chewing for days! I love that you can add soft treats or doggy toothpaste to the grooves in these. The raised bumps on the toy are also supposed to help clean teeth. A dog toy that helps with bad breath? I will take two please! Plus, love that these can be cleaned easily, even in the dish washer, and have long lasting bacon scents that my girl loves.
In all seriousness, these are strange looking but very functional chew toys. They do not make a mess (other than my dog drooling all over - haha). You can even add doggy peanut butter! Perfect for big dogs and aggressive chewers. I would caution against using for any elderly dog and or dog that doesn’t have strong teeth.
Good value for the price (a little over $5 each on sale) considering how long these toys last. Also a good gift.

Dog approved!
My dogs love this. This is the 3rd time I have bought them. They are entertained for hours and keeping their teeth strong.
They pay me no attention when they have this toy. 😂
