Rod, I may have a pair, I will look tomorrow.

**chewychevy67** · 12-19-2018, 11:32 PM

I purchased 2 from rock auto. Thanks for that!

**70STOVEBOLT** · 12-19-2018, 11:47 PM

Ok glad you found them

**PDXk5** · 12-20-2018, 01:31 AM

Corvette Central sells them.

I actually bought those and they are not hard like my Nos 2" Ramhorn ones. They look layered like the fiber ones. Not what I was hoping for. If I press hard with my fingernail it makes a mark. If it was solid steel i should not be able to do that. 70STOVEBOLT please post pictures of yours. I may take them as well.

Hmm, that's disappointing. I plan on going the route of 2.5 inch ram horns and was thinking I had a source for the donuts. Thanks for clarifying. I wouldn't want to purchase them either.

70STOVEBOLT, you wouldn't happen to have two sets for sale would you?

MAHLE F7139S Sintered Metal Info
e. Seal Ring Type "B"; with 2.5in Pipe; Sintered Metal; Manifold to Exhaust Pipe
this is rock auto part number the have them on close out

**chewychevy67** · 12-20-2018, 11:33 PM

I did purchase a few from rock auto at that exact part number. When I get them I will post pictures. The corvette central one said metal as well so now I'm not sure. That's why if 70 stove bolt has the real metal ones I want to make sure I get a set. Hate the cheap fiber ones.

**70STOVEBOLT** · 12-20-2018, 11:36 PM

The ones I have are Mahle, I can post pics tomorrow. I only have one set I think.

**chewychevy67** · 12-20-2018, 11:56 PM

I'll let pdxk5 have the ones 70STOVEBOLT has if he wants as he needs them as well. I will see what I get from rock auto 1st.

These look good from the photos. Chewy let me know if they are solid when yours arrive.

**70STOVEBOLT** · 12-21-2018, 09:24 AM

The ones I have are the F7139S which have been discontinued by Mahle, they only offer the fiber type now. I thought I had an unused set but they are slightly used, I ran them with the manifolds for about 500 miles then switched to headers. If anyone is interested let me know and I will get pics.

**PDXk5** · 12-21-2018, 03:03 PM

I'm interested. Please post pics.

**70STOVEBOLT** · 12-21-2018, 03:19 PM

Will post pics as soon as I get a chance to take some, will be this evening.

**leddzepp** · 12-21-2018, 04:46 PM

I bought a pair at autozone last year, I’ll look for a part number. Solid steel is all I will use from now on. They work very well.
