Schoenfeld headers have been around forever!!

If that's the case it should be well known they don't have flanges...

 

Been around 20-30 years.. Headers we always ran on our dirt track cars.

 

these don't leak. have an exhaust shop stretch an end to where it slips over the collector pretty tight. these clamps mold to the overlap and seal it. it also doesn't crimp the pipes to where you have to cut them off later

 

None of the band clamps on my truck OR my car leak and hell the clamps on my truck are cheap ones from advance auto.

 

Do those LS1 into 88-99 GMT-400 truck headers fit well? I have seen them forever, but haven't needed a set of them.
Lots of exgaust shops will cut off whatever comes on the ehader and use their own connections. At least in my experience. You can successfully weld on coated headers, just take your time.

Did you look at the picture of them? It is pretty easy to tell there are no flanges on them.

 

i've never bought a header with a flange installed...even my 1,200 kooks. i'm outraged!

 

Shoenfelds have been around for a while and make good quality parts! They dont sell headers with flanges because they are primarily for dirt track cars and other vehicles that are for racing applications or offroad use that would either utilize an open header exhaust or a custom exhaust setup. I am originally from Fort Smith Ar and have many friends that use them on their dirt track cars with no issues at all.

 

My Pacesetters have a y pipe that has a 3" ID where the headers have a 3" OD. Slip fit and put on a band clamp. Easy breezy.
