Popped my header cherry.

Question for those that have these.
In the auction they show these as having a 3.5" flange after the Y. Since these are for early trucks wouldn't these have a 3" final size? I am looking to put these on a truck with a factory 3.5" system and trying to find out if they will bolt up or if the ad diagram is incorrect.
Thanks

What did you make that out of? I just ordered a set of these headers and will be needing to keep my wires off the primaries.

I'll take a link
+1. I think the ad is incorrect since OP should have a 3" system.

They might be calling the outlet 3.5" because it actually does slightly flare out right at the actual flange? Probably a half inch. See pic below. I know my stock Y pipe did this as well...

Its stout, but can be bent and drilled to make the desired bends. Worked great.

I just got mine in and I must say the quality is very nice. The primaries measured 1 5/8 and the y pipe and collectors are 2.5". So it looks like I need to pick up 2 2.5" band clamps. Did you use a bolt to block off the egr?
