How do you tune a merge once it's made. On a pure race application, when using slip on collectors you can play with primary lengths by adding extentions to the primaries. The merge itself requires replacement of the cones (adding and subtracting length to the straight portion of the cone and also playing with the size of the opening at the collector itself. Unless you're drag racing with open headers it's a waste of time playing with the merge, especially when there's an entire exhaust system hanging off the end of the headers.

I wouldn't be pissed about the merge collectors (Although they leaked like a SOB when I had them on my 00 Z28, and they were even tacked)
I would be worried that they are using 304 stainless which is the cheapest stainless you can use in the 300 series. It does not have the high temperature fatigue resistance that 321 does. That is why I went with the "other" header company. They use 321. I had two sets of Edelbrock on my car. The first had the Ti-Tech coating came off after two weeks of driving (No rain or snow). The second set didn't fit right and I couldn't drop the trans with them still installed. But the coating was fine on that batch

Richard,
Can you clarify a few things for me?
1) Are the collectors welded in by edelbrock and leak free?
2) AIR tubes present and available for 2002 year cars?
3) Slip on Ypipe or 3 bolt flange or similar?
Thanks!
Chris

and yet you think I'm the idiot what ever!

Here is what I found....
http://www.edelbrock.com/automotive_...petition.shtml
Victor Series Drag Race Headers
NOW AVAILABLE WITH NEW TI-TECH FINISH OR CERAMIC COATING
These new drag race headers have innovative features to maximize power potential in competition. They are engineered with the correct firing order pulse sequence in the collector, unlike most competitors' headers. The 3/8" thick laser-cut flanges are robotically welded and contoured for a perfect fit. New fully welded headers include O2 sensor bosses and collectors for a no-leak installation right out of the box.

bump.
anyone know if there are any fully welded sets of stainless steel headers coming out WITH AIR provisions for '01-'02 f-bodies? if so, i'd be very interested in a set for the future

I spoke with the tech guys at edelbrock.
The only fully welded ones are the mild steel with ceramic coating or ti tech finish. They also have standard (not merge) collectors. The stainless Ypipe is available however.
The stainless come with NO emissions fittings and only come with slip on collectors.
I am probably going to go with the ceramic coated mild steel headers ones with emissions fittings for an 02 and the stainless steel Ypipe.
