Title: Help looking for a flange to buy
Post by: 1LOW4X4 on March 04, 2011, 09:24:40 AM

hey guys, I've about got everything figured out except the flange.

What I have is a Hooker header with a flange on it already.

What I need is to buy a flange that will fit on a 2.5" pipe, and bolt up to those headers. Like this.

I see they sell a few different flanges on summit, but I cant find what im looking for.

In the pic above (with the red circle) is that a flange on just a reducer, and then welded up to pipe? How do you get the flange to hold on the the reducer if there's no lip?

Well crap. Just found these....is this what I need?

3 bolt flange, 2.5", and I'd just bolt it up to the header (with a gasket) and then weld my pipe to that?

That's what you need. Make sure you bolt up the reducers first and work your way back when you make the pipes.

I use similar to these
