    11104 - FlowTech Headers is rated 3.0 out of 5 by 3.
    Rated 5 out of 5 by from Outstanding fit I read several reviews in regards to what headers would fit on my fourth generation Monte Carlo I took a chance and they fit exactly the way everybody said they would they're awesome they sound good

    Rated 3 out of 5 by from Great fit I purchaced my headers about a month ago and they fit great. I didn't have to modify anything. The only problem was when i opened the package they were dented and scratched and all of the hardware was out of the packaging. It looked like someone purchased them and then returned them after they couldnt get them on.

    Rated 1 out of 5 by from Disappointed They didn't fit at all they hit the frame on the drives side so bad a couldn't use them and on the passanger side they were right up against the transmission bell housing. I waisted $150 on headers that I couldn't use
