Fitment Notes:
- Pontiac V8 Engines Only!
- Will not fit Firebird/Trans Ams with column shifted standard transmission.
- Must modify stock exhaust to retain catalytic converters.
- Will not fit Ram Air vehicles.
- End holes on head must be drilled and tapped to ensure proper seal.
- 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 recommend 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 Coffee, Tiny Footprint!
Color: A-Brushed Silver
I love this compact espresso maker! The 20-bar pressure pulls a rich shot with excellent crema every time. The milk frother is powerful and creates perfect foam for lattes and cappuccinos. It heats up very fast, looks sleek in stainless steel, and doesn't take up much counter space. The 44oz tank holds plenty of water for multiple drinks. Highly recommend for the price

Great espresso maker
Color: A-Brushed Silver, Color: A-Brushed Silver
I’ve been using this espresso machine for a little while now, and honestly it’s become part of my daily routine. It heats up quickly, the espresso comes out rich and smooth, and it’s nice being able to make coffee at home instead of spending money at cafés all the time. I also love how easy the steam wand is to use when I want to make lattes. Overall, it feels really sturdy and looks great in my kitchen too.

Great Coffee, saving Starbucks money everyday
Bought two of these 14 months ago:
1) Makes a great cup, hot, very tasty; I work in the coffee industry, this is a great mini version of a proper espresso machine
2) It's miniature, especially great for small kitchens. Stainless steel, very easy to use and clean
3) The milk steamer is average, almost a gimmick
If what you care is the classic black coffee with milk this is a great option, definitely good value

Must have for coffee drinkers will love
The coffee drinkers wet dream. This works so well and it one of the best additions to our house. The ease of use and the way it works make my husband and son just love their coffee. I don't drink coffee but I know this machine is too notch as they swear by this. Quality as well as workmanship are bar none.

Solid, but not without fault.
Got it on sale for 90$ and honestly it’s been pretty solid. After making espresso, the grounds are always left watery, but that’s just a design fault in trying to achieve more pressure. The coffee is pretty consistent and solid, a pretty good value for what it is.
My main issue is that it leaks water now randomly after about a year of use, which ultimately warped the coffee station it sat on. I know some bigger brands that begin leaking after time as well. So for under 100$, I got what I paid for. this saw some heavy use and got the job done. Probably wouldn’t buy again though.
