Are the new ARH headers not equal length?

Nevermind I checked they are stepped up and don’t seem to be true equal length but pretty close.

When you lay them out for 4-1 they land pretty close to equal. we wanted a slightly longer runner, but after this initial test we will optimize the collector to runner length if needed.

what outlet diameter will you use? I’m curious if anyone will develop a true 3 inch system from collector at header all the way out including exhaust piping.

Ours is a full 3" system, from the collector all the way to the back.

So I had Concept841’s prototype headers and titanium catback installed a few days ago. Sound is ridiculous and way more high pitched. First headers I’ve heard on a C8Z that actually add to the high pitched sound instead of sounding more muscle car like. And the headers alone added 20whp on my car on the dyno.
