Looking to replace 2 sets of mercruiser stock exhaust mainfolds that have (2) 3 inch riser extensions per manifold for a total rise of 6 inches above stock bravo riser heigh. I know that Gil made risers for this application on Formulas with HP500's and 525SC's in the early 1990's. Anyone have two sets they are looking to get rid of? does anyone else make a 6 inch taller riser? Thanks as always.

I have 2 pairs of Merc/Gil manifolds for sale.Come complete with manifolds,risers,mufflers,and all parts for the switchable muffler system.I would have to measure the height of the risers.I think they are standard. Asking $2200.00 or best for entire system. Ad is on speedwake.com under the parts classified section. Let me know if you are interested.

Do you have a picture??

Stock exhaust:

Chris - The risers that you have won't work for me because they look to be for standard bravo setup which most people have ( but not me). I also installed HPI mufflers this year. If you would separate them and just sell the manifolds I would be interested in the two pairs of manifolds. PM me.

Yea, I would sell just the manifolds.I tried to PM you but since I am not a Platnum member I cant.I would like $1600.00 for both sets..Or make me a serious offer. It is easier to get ahold of me at this [email protected] me know..

I have the same problem, 93 Formula 271, I just need one set! I am thinking of getting a standard set and cutting them and welding up a longer rise in them. Anyone ever try it?

Now have manifolds (thanks Chris) but still need two sets of 6" rise gil ss risers for bravo model number 902465-6.

Someone here has to have some of these around from an exhaust changeout.
