    Awesome if u like attention . helps cool engine compartment (reduced in hull temperatures by 20-30deg)
    They sound awesome but can be extremely annoying if u have a passenger .
    Sounds like a crotch rocket . gives slightly better spool up

    If that's truly it in the picture . don't waste ur money . u will not see much gain if any since its not a equal length header. With our Hondas being turbo charged u have to keep equal length or exhaust will not flow as smoothly to spool up turbo

    H2O definitely reckon it does help acceleration and and cooler running temps.. But still cant find any info of any1 that runs this manifold to verify those claims. So far this is the only aftermarket water cooled manifold i can find.
    With new oem manifolds on backorder from manufacturer and used ones near non existent I'm looking for different options at the mean time.

    Looks good but could have salt water issues . hard to say but they do have a return policy if u can make & preform a water test .
