Actually Doug Thorley still does manufacture the LS4 headers, but they only make them to order since there is such low demand for them, I called them in April this year and ordered a new set, they're still out there just take a few weeks to get a build slot on their assembly line. 👍
I just picked up a minty 08 GP GXP and I'm finding that the header market isnt quite what it is for the f-bodys. Haha. This might be the only way to go when i can no longer leave things stock.
@@LS4King Has there been a delay of some sort, or did they just sell like hotcakes? I'd love to get my hands on a pair. Also, is a sound video planned? Thanks
This is a great and simple modification, this is what the W-Body needs for all their engine options.
Beautiful exhaust upgrade that has to free up quite a bit of power.

That is great to know! Thank you for sharing that info.
Huh??? How exactly did you come to discover they do ls4 headers?
Great information glad to see you back at it
Great informative video. I don't have an LS4 but it helped a great deal. Subscribed!

Looks beautiful.
So i believe you like Vibrant v bands. I wonder how hard this would be with Maximizer headers as they are stainless already.
The Maximizers already have a decent flowing merge, but yes much easier to modify. Just need some 308 filler.
Can you send me the full layout of everything I need to get a supercharge on my 2007 Monte Carlo ss
Hey what’s that Intake manifold about? Is it a northstar supercharger manifold adapted to ls and capped?
whats done to that motor ? is the lower end built ?
3" true dual or bust. my 1982 Chevy S-10 LS swap needs a x pipe or a h pipe
How caN we buy the kit from you
when will your stainless manifolds be available
We’ll have a full shelf of them ready to ship in December with 2” and 2.5” discharge.
Cast stainless?@@LS4King

Would this also be beneficial for the 3400 and 3800?
Absolutely
@@LS4King perfect. I’m supercharged 3800 swapping a grand am gt
Bro pls make these
You did I deleted that comment. What formula for material thickness to amperage do you use?
My formula is experience haha. I set my machine at 80 amps and run it about 65-70 on the cast manifolds.
@LS4King I need to experiment. Have you used purple tungsten?
@@alexsimz5933 i have but I prefer my blue
Can I take your crossover?
