Volvo 7.4L Exhaust manifolds/risers

[bruceb58]

For a 1997 Volvo 7.4L, what are my choices for aftermarket manifolds and risers? <br /><br />I see versions for Mercruiser but don't see any for Volvo.

OK...I have the Volvo numbers and what I believe are corresponding Sierra numbers. Can anyone confirm these?<br /><br />Exhaust Riser<br /> Volvo 3857944<br /> Sierra 18-1909 ??<br /><br />Exhaust Manifold<br /> Volvo 3852362<br /> Sierra 18-1898 ??

I have found out that the Volvo number for the manifold has changed to 3861459.<br /><br />Don, do you have any experience with aftermarket ones for the Volvo 7.4L.<br /><br />According to the Sierra Rep, the part number that I had for the Sierra manifold is a universal manifold which will require modifications to my exhaust system.

universal fit is universally gauranteed to fit nothing correctly. the risers from seirra will work but last set I replaced the manifolds had to come from volvo.<br />make sure the replacements you get are direct fit or the fun and games will begin.

That is why I am not going to buy them. I want the exact fit.<br /><br />I traded emails with a guy at OSCO. He says they are in the works but right now it's just on paper and nothing is being made. <br /><br />Must not be many Volvo 7.4/8.1 out there.<br /><br />I found the manifolds for $320/each and the risers for $172/each for Volvo parts. I think that is the best I am going to be able to do
