    11504 is rated 4.3 out of 5 by 4.
    Rated 5 out of 5 by from Perfect fit, nice header for a great low price Bought these to replace the mid length headers that were on my 89 c2500. The fit perfectly. The only thing I had change was having the y-pipe reworked as it did not line up. Minor inconvenience but to be expected when changing an unknown brand of header to a new set. The hardware provided seems to be pretty good. Overall I'd recommend these if you want a good set of inexpensive headers.

    Rated 5 out of 5 by from Headers didn't fit my project. Sent them back.... got a full refund. Thank you.
    Date published: 2017-10-07
    Rated 5 out of 5 by from Great service. Although I had to return the headers I bought because they were to wrong fit. Customer service was awesome. I would buy from them again

    Rated 2 out of 5 by from not so happy I was excited at first but then I got a little upset. They got the drivers side but not the passenger side I managed too stop it from leaking but I am looking for a new set again because they don't fit..
