mercruiser gil manifolds
 

these are off my boat. they pressure test good. i changed over to the hardins marine shortie headers for the polished look.
they are salt water used and show some corrosion here and there but all gaskets seal. they can use a couple of heli-coils.

$500

hey Tim, it didnt pick up any speed. they sure do look great though!

are they taller than the gills ? whats with the 2 wedges ? are those stock bravo exaust holes ?

they are the same as the gils as far as the dimentions. the wedges are for my tailpipes to fit

where did you get yours and how much were they if you don't mind me asking ?

i bought mine from a member on here who had them sitting around

dam , I miss all the good stuff

TTT make me an offer!

I was thinking of getting two sets of hardin headers for my cafe, how do they sound compared to the gil manifolds? I have dry tailpipes Im wondering how they will sound compared to cmi headers. Any issues with water reversion?
