those chps look like they just fall into place based on the video. I pulled the starter and motor mount on the passenger side to get my 1 7/8 Kooks in. Others have apparently done it with out removing anything, but I don't really see how. The fitment on the Kooks is perfect, just a bit of a pain to get the passenger side in. At least it's pretty much a one time thing so not a really big deal.

The other obvious advantage is less overall restriction. One advantage of flat-plane V8s (or any engine that has even firing on its exhaust banks) is that it can run very-short-primary headers without as much interference of exhaust pulses from port to port. Nobody is tuning primary lengths for resonant tuning anymore, especially with turbos. Everyone is trying to get turbos and cats as close to the port opening as possible for various reasons. |

Pray tested 3 different set of headers and Speed Engineering made the most power by a slight amount that he chalked up to being variables. Price, fitment, and quality are the only 3 reasons to consider when shopping.

1300 hundo for headers? These seem nice but wow, thats some high dollar stuff.

Due to the odd fire nature of the engine and kind of tight fit, I like the Billy Boat E
Tri-Y Design: https://www.bbexhaust.com/shop/chevy...der-fdom-0365/ But who really knows, the Tri-Y tubes pair ports furthest away from each other, so there is no primary port flow interference with the pulse (fist merge) between the paired ports, the second merge pipes are much larger, so think of this as "extending" the merge point further down via gradule flow expansion. So at the point two ports are flowing at the same time the effective cross section is twice as big. I will note the current thought in Honda B and K engines setup is intefereance merge Tri-Y where the pipes are selected to purposle put two exhaust pulses together. The thought is to keep the energy in the pipe (pressure and heat are energy) and there really is no "reflective" extraction wave on a closed exhaust system, as such waves are generated at the exit point to atmosphere. No way it works (interferance merge), except it does and my current 275 engine HP B engine NA 2.1 liter uses such a header to good effect. https://www.ebay.com/p/19017008225?i...BoCAegQAvD_BwE all inline 4 firing orders are 1-3-4-2, you can see that 3 and 4 are paired. The exhaust pulse of 4 will really start hitting when 3 is tapering off, so you get one really long and strong pulse. Can't work, I know right? Sorry for the threadjack. I'm merely talking theory, not like I'm selling headers. The Complete Street look to have nice bends and a gentle merge collector and that is basically where any potential power gains will come from. What I do really like is the nice straight carry from the exit of the head before the first bend, there is a least one cheap brand that really bends the header tube too soon. Sure you can get more room to fit the tubes in but I like a good 1" or so before I bend the tube. I also like the ball connection as this exhaust is basically one piece and there is some minor movement at this ball which is good.

Andrew said on his channel that they actually picked up a little power vs the kooks on the treel1. I havent saw a video showing the dyno or graph though.

able to use the stock wires is a plus. I have modified stock wires on my 1 and 7/8 Kooks, I made a total of two brackets to loom the wires and modified 3 total stock wires as shown in the picture. Not really all that hard, but how many shops are going to do it? This header looks to work well with stock wire. Once again, not hard (I finally got bent ceramic boots), but shops ain't gonna do it.

So while price, fitment, and quality are in your opinion the only things to consider that doesn't make it a fact or rule. Others may value the power gains from one over the other, however minimal or not. Tsp provides both value, good fitment in the latest batches, and apparently the most power.

I'll be very interested in them once some cats come in with them.
