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.

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.

Wonderful grinder:
Color: Silver
This is one little powerful grinder. It holds 30 grams in the glass jar which is perfect for 2 cup 10oz cups. It has a dial to adjust the grind. Great for two! It works great. Really good purchase. It is a labor of love.

Great coffee grinder!
Color: Silver
Amazing product. Easy to use and has different grades of grinding. Zero noise compared with an electric grinder and more control of the results (consistent). His size and weight make it portable and easy to carry.

Quite good as a start grinder
Color: Silver
Very good burr grinder with very functional adjustments. Holds the perfect amount in 1 go for my pour over setup. My only critique is that is has 3 unconnected hopper sections that are quite small and hard to hit. I have to be very careful to not spill and one can fill before the other 2 causing some difficulties closing the crank, but it just takes some self adjustments to get around. Overall I'm very pleased with it for the price.

Great Quality, Great Price.
Color: Black
I have used this for a few days now and it works great. It is very well made and has a large range of adjustability. It is quite small and easy to store. Definitely worth the money.
