Default Speed Engineering down/forward

Does anyone have a measurement of how wide the Speed Engineering headers are when bolted to an LS in the down/forward configuration?

I’m hoping they will fit between the frame rails.

Thanks

I’ve reached out to several venders that sell them, along with Speed Engineering themselves, and none of them have the answer…

I’m pretty confident someone on here has used them… I’ll be patient…

Are they like the standard Chinese up and forward style headers? I just swapped from a set of Chinese to a set of flowtechs and if there's any difference width wise I couldn't tell. If this is the style you speak of I can measure them in the morning, I have them mounted down and forward.

These are the SpHeaders I’m asking about.

The widest part of mine, which is the front most primaries, measure between 27-28". I also have the 1-7/8 primaries so the smaller set maybe less.

Thank you very much for taking that measurement and replying to a random guy on the internet. It appears that they will fit in my frame.

That’s what these message boards are good for.

have a great weekend!
