Based on what?
So long as the diameter is neither too wide nor too narrow (2.5" sounds about right, N/A for this engine), the bends are mandrel, the path is reasonablly straight, and the flanges seal well, why wouldn't it make just about as much power?
Seriously, how much R&D really goes into one of these CBE's? Does it go through more than 2 iterations and a few dyno runs?
The most expensive thing here are the materials -- higher quality SS will cost more (and titanium or inconel will put the price waaaay up), but the difference in heat retention or weight isn't going to acount for a range of like $1000 bucks when it comes to performance. Like, seriously, if this made 3-5 less whp at peak, is that extra few ponies worth another grand?
The only issue I see in the set up is the flange right at the x-join. A straighter path with a nice 2-1 Y merge collector before adding a flange might make a few whp difference, but so long as that flange doesn't leak or isn't a bottle neck, it should be fine.
Hey, worst case scenario, maybe the "names" will feel the competition and reduce their prices -- they'll move more units and we'll all have more options with better prices. Capitalism at work
