Donut style flange SLP uses
Where can I get a pair of these 2.5" flanges that take the felpro double bevel gasket?
I thought my ball flanges would fit the SLP's but they don't, and I need to finish making this y-pipe.

Re: Donut style flange SLP uses
I wonder if something like this would work:
http://www.ebay.com/itm/Hedman-Heade...ht_1469wt_1163
If I welded a small stub in it to center the donut gasket??
The SLP headers don't actually have the stub on the header side, but on the y-pipe side. I wonder if just two bell ends would be fine with a gasket?

You might get it to work.
However you'd probably be a lot happier in the end if you buy two Vband sets and weld them on instead...

Re: Donut style flange SLP uses
OK!
So I used hedman # HED-21123 reducers which are around $20.
I Welded a 2 1/2" pipe inside the opening to keep the donut gasket centered like SLP did. Works like a charm.
The donut gasket I used is Felpro # 9587, which is 2 1/2" ID 3" OD, twin bevel.
For the bolt flanges I bought some on ebay, part # SF008. (forget the mfg) which worked out great.

Re: Donut style flange SLP uses
Hurricanes suck.
Anyhow, back to the car. I got a chance tonight to put a bunch of bends together with a flowmaster Y collector. This is just tack welded, but you get the idea. I'll weld it up in the next couple of days then put an 02 bung in the Y for the wideband.
2 1/2" pipes, into 3" merge.
I'm not using a thirdgen oil pan on my 400 block so I had to drop the crossover pipe down more than usual. It's about an inch below the k-member. Still should have more clearance than the long tubes did.
