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.

- Leakproof O-Ringed Port Seals
- 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.

Amazingly strong and versatile
Size: 2.5" & 4" - 4 Pack, Style: Open Hooks
I saw these advertised on Instagram and immediately purchased a 4 pack. I really wanted them to work but after trying them on 4-5 different steel surfaces I couldn't'[t get any of them to stick well or hold anything heavier than a wet towel. Maybe a bad batch? A shame.
The company took the time to reach out to me after seeing my first review where the hooks wound stick to metal poles in my studio. I definitely was not expecting them to reach out to address my issues with the hooks I purchased and returned. After trying the new replacement hooks out I now could not be more impressed! They are strong, well made and easy to use. The hooks and the magnetic baskets are phenomenal and I highly recommend them. I did a test with the hooks, which held a 75 lb weight with no issues on the side of a craftsman tool box! It seems that any early product issues are fixed. The customer service is fantastic and they really took the time to address the issues and keep their customers coming back happy. Well done! Gator Magnetics is definitely a class act in my book!

25 lb hanger doesn’t hold my Echo trimmer
Size: 4" - Red, Style: Open Hooks, Size: 4" - Red, Style: Open Hooks
Purchased the holders for my Echo trimmer and hedger but the tines are not long enough to hold the Echos. A picture in the description shows a gas powered unit hanging which is why I bought the hangers. Buy the larger 45 lb hanger for trimmers. Nice hook but I’ll probably send them back if i can’t find a use for them soon.

Handy
Size: 4" - Black, Style: Open Hooks
I use an ocean container for storage and have some things that need to be hanging. These are perfect for any place you are unable to drive nails. I bought the stronger ones and have had no problems. Ordered more after trying them.
