Well... a lot of you guys on here know about other fords...

On mustangs there are H-Pipes and X-Pipes..

X-Pipes are a little bit louder and can get a lil raspy... but and H-Pipe gives no rasp and is very very deep....

I was wondering if we could make an A-Pipe... just like the Y-pipe now but with a pipe inbetween before they connect...

Y-Pipe

Imagine a piping before they connect.... it would seemingly have no purpose but according to a lot of car people i know it would be great for low end torque and would sounds very very deep.

It would serve no purpose outside of causing flow degradation and turbulence.

An X-pipe or crossover pipe is put in to balance exhaust pulses between cylinder banks using individual exhaust pipes. (true duals)

When using a Y pipe there is no "true balancing" between cylinders. Matching pulses (not overlapping) is about the best you could hope to achieve. This would be accomplished by the Y-pipe pipe shape and pipe lengths.

Also spliting the single pipe at the outlets (quasi-dual) is just for looks. A properly sized single pipe would make the same power as a quasi-dual would...
