    We might have headers, but they don't come with a 5.3 and I don't yet have a transversly mounted 5.3.
    I drink..so consider that when reading my posts.

    I'd pay the $100 more to have something that I know will fit. OBX can be very hit and miss.

    How hard is it to do headers on the LS4?

    theres a detailed write up on ls1tech for putting headers on an ls4 and it really doesn't look hard...just time consuming cause you have to remove several things

    I bet they fit just as good as the OBX headers for the 3800.

    Let's see...


    I remember OBX passing off crap soon after the first Fast and Furious came out if I remember right...because my buddy bought a header for his 420A Eclipse from them back in high school...it worked...after love from a hammer.

    Im still confused why the cheep ebay headers for the 3800 include what looks like a piece of rubber hose and a bunch of random hose clamps.

    Considering options for the ls4 community as far as headers go at least now there is another brand which help drive down the ridiculous price. Kinda like when slp came out with 3800 headers at 700$
