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.

  • Improved Exhaust Scavenging for Increased Performance

  • Include All Mounting Hardware
  • Constructed of .049 cold roll flash mild steel tubing

Fitment Notes:

  • Will NOT fit with manual transmissions.
  • Will NOT fit C6 transmissions (but fits other Automatic Transmissions).
  • 351C-4V engines only!
  • WILL fit models with AC, Power Brakes, and 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.

Great shoes for everyday wear and baseball practice
Size: 1 Big Kid, Color: Blue Orange a
So far, my son has really enjoyed these shoes. He wears them every day, and they’ve held up pretty well, even with baseball practice. They seem comfortable for him, and they’ve handled regular use better than expected. I’m very happy with the quality and durability so far. For everyday wear and active use, these have been a great choice. I’d give them 5 out of 5 stars and would definitely recommend them.

Awesome shoes for an active kid
Size: 6 Big Kid, Color: Blue
These shoes are absolutely AWESOME. We've tried a lot of these lesser known Amazon brands as well as big brand names and these Kubuas are great. Comfortable, light, can be worn all day. My 10 year old is on his second size. The old pair that he's outgrown now is still in pretty good shape. Highly recommend!

He loves them.
Size: 4.5 Big Kid, Color: Black Orange
Great construction and very durable. I’ve got an 8 year old boy who loves to play rough. He wears them through mud, grass, gets them wet, anything you can imagine. They clean really easily, which is a lifesaver when you’ve got an 8 year old. He loves the colors and his friends think they’re cool, which is a bonus. They support his arches well, fit just right, and are true to size. These can be worn as daily walkers, gym shoes, running shoes, or when he wants to look fly. These grip is strong - great for gym class. Very affordable and well worth it. Shipped quickly. Multiple uses for sports, walking, basketball, soccer, whatever. The laces are tough and the tongue is well constructed, as is the heel and the sole. Works perfectly.

The BEST kids tennis shoes
Size: 11 Little Kid, Color: Black/Green
I just bought a second pair of these for my son. The first pair lasted a whole school year, which is pretty good for an active 4 year old, and he still loves them though they look a bit beat up. Got him a new pair for his birthday and he’s so excited. Worth every penny. True to size and they are apparently very comfortable.

I will keep buying these
Size: 3 Big Kid, Color: Black Orange, Size: 3 Big Kid, Color: Black Orange
This is the third time I have purchased these shoes. Every time my son grows out of them I buy the next size up. His favorite color is orange, so he loves the look of these. They are also soft mesh around the toes, which he loves so he can wiggle his toes. These are durable and well made. The pair i purchased before these is still wearable, just too small for him now. These are his daily shoes. The price has gone up since my first purchase, but they still are not unreasonable for how long they last. He is an active boy. He climbs trees, runs, and plays hard. So for any show to last 6 months when he wears them daily it shows the durability. It also shows that these shoes have tread on them thay stops him from slipping. He is able to move around freely and never has issues with grip. He puts them on without difficulty.
