..... Who knows who might be making/selling LS swap race headers for our awesome C4's ... I'm looking for 1 7/8" stepped to 2.00" primaries or non-stepped with 3" collectors .....

My search only found 1-7/8
Looks like your step is going to be a custom make.
What's funny is the boosted LS rides. pushing near 800 plus. A fairly common LT swap trend.
the reverse flow cooling/ timing Mgt gain.
Nets better results.
As good as the LS aluminum block is.
Either LS iron trade.
Good ole iron handles much more HP trouble free.
These are meant for a C5 but they will work for a C4 if you cut off the collector and weld on new 45 deg bends. Also one of the primary tubes on the passenger side needs dented in. But for the price I was very pleased with the quality. They used to sell these on ebay under the brand name CX Racing or something like that. But the only place I can find them now is off of Aliexpress. But don't let that scare you off. I order from there all the time. But these are just 1 7/8 primaries with 3" collectors.
One piece of advice about welding new collectors on these is the Blue Demon 308LFC-O flux core wire worked pretty well with it.
Im using the BRP Hotrods 1 7/8 stainless - good quality good fit - go to 3" collector.
Chatter on LS swap group is that there is a wait on these now, hit or miss if in stock.
Billy boat do a LS swap header, but mid length collector.
