I was watching Carcass a couple days ago and one of the guys on their said that the LS factory exhaust manifolds are cast steel, not cast iron. Right away my mind started bouncing around in my skull with a bunch of weird ideas.
If they're steel can they be cut and welded like steel? Can steel parts be added to them? I've got a couple sets to play with when the weather warms.
My first thought was can the outlets be easily cut and repositioned because they're steel? Maybe we won't need to throw money at Holley if someone comes up with a quick mod of the outlets that can be done by simply cutting and welding.
Back in the day we used to split inline 6 intake and exhaust manifolds that were cast iron and braze them. Not the most durable or pretty items, but it beat spending $30 on custom 2 outlet exhaust manifolds to run true dual 2" exhaust systems to the lake pipes. Stick welding the pipes was tricky, too.
