No doubt we've all seen the EMC motor by Kaase with 16 primary header tubes all
merged down into two collectors. No one can argue there is not power to be found in merging header tubes and even the exhaust pipes as seen with X-pipes or Y's into single large exhaust. The by-product of x-pipes on the exhaust pipes is dicing up the exhaust pulses that essentially double the number of pulse sounds leaving the car so an 8cyl sounds like a 16. The effect is you hear a lot more cylinders pulsing but each is obviously weakened. This motor in video takes it a step beyond:
This is a 447Cu In/630HP Windsor in a very seriously built Mustang that has some interesting ideas. I believe the a fair part of the car's F-1 sound comes from the X-pipe flowing into Dyno-Max Bullets and into reversed Y-pipes flowing into about foot long exhaust terminations that dump in front of the rear tires. The video'rs are obviously doing there dam'd best to enhance the F-1 sound (via running through the tunnel and bouncing it off the rev limiter//peak power 6200). and of course the as mentioned 8 Hilborn stacks combo add to F-1 sound.
I believe going back from the typical cars dual exhaust outlets to Y'd quad exhaust outlets further adds to the screaming pack of bees sound.
I'd like to know if this reverse Y'ing at the end of the exhaust pipes into quads is detrimental to power output vs the undivided pipe. I figure it's got to hurt, but how much? ..............perhapd someone with a dyno?....hint
BTW I love the sound of merged pipes though I recall being at Daytona when they were introduced I was repulsed by the sound (then a NASCAR car flipped and Circle Track Magazine had the inside exclusive showing the X-pipes on the upside down car in the air) Just takes a while for the sound to grow on you and when you know it makes power......
