Overview:
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.

Still going strong after three months of Doberman teeth!
Color: Green
This was one of the first toys I purchased for my adopted 4 year old Doberman Pinscher. It has been chewed, and chewed, and chewed some more. This is one of his 3 favorite toys when he has to go in his crate. As of yet there are no significant teeth marks, holes, or missing pieces. It is solid rubber, light weight compared to a similar toy he has, and just the right size to carry around in his mouth. He seems to enjoy the sensation the little rubber nubs have on his gums when he chews it. We have also used this toy to play tug of war and fetch for the same reasons listed but also because the neon green color is easy to see especially if the dog gets distracted and leaves it in the yard. When playing fetch the weight of the toy does not lead to rotator cuff surgery with repetitive throwing on the part of the dog's human! When it gets too dirty and slimy for my tolerance, it is easily washed in the laundry room sink with dish detergent and a sponge always returning to its Spic n' Span original appearance. If and when he chews this one up, I will not hesitate to replace it.
Top 3 Likes:
-Sturdy, holds up to chewing, used as a crate toy as it poses no threat from dislodged pieces
-Bright color aids in finding it outside
-Comparatively lightweight, easy to throw, and easy to clean
Top 3 Disikes:
-Potentially an aggressive chewer could dismantle

Fantastic toy for strong chewers
Color: Green
This dog toy is FANTASTIC! I have a pitbull that is a STRONG chewer and not even a piece has come off! This toy has lasted the longest of any dog toy I’ve ever had! I got one and then immediately ordered another one! Highly recommend

Maybe for XL breeds.
Color: Green
This pull toy is too heavy for my 49 lbs Foxhound/Beagle mix. The “beads” are very sharp, and he didn’t want to put it in his mouth to chew on or play tag. I don’t think he’s picked it up since the first time I gave it to him. Extra large dogs may love it, but it was just too large and heavy for my dog. He was very unhappy with it.
