Back pressure?

Just thought of this regading Xpipe upgrades. Instead of having them intersect in the middle......have them run independently in a X configeration. I would think this would cause less turbulance.

That is the correct path, yes. The angle of approach of X-pipes is very poor. Think of a figure eight car race. Those masses meet at a 90 degree angle. How much damage would occur if the meeting point was nearing zero degrees. The masses could merge, and separate into their proper directions, without major interruption.

The distances of primaries, collectors, and cat pipes, have very little affect on "tuning" of a crossover. For real racing where two, or ten horsepower, can win races, tuning those things would be worth it. That kind of tuning would take countless hours of hard fabricating work. It would not be worth it for real world street vehicles. That's the kind of stuff that car manufacturers spend millions on, and raise vehicle costs.

Our Explorers are perfect vehicles for a better crossover, the pipes are parallel. Regards,

WELL SAID I am glad someone else understands this. Whenever I say this on here i get ridiculed and flamed so expect same. I have tried explaining it so many times so many ways. Even got into the science of scavenging a few times. No suck luck, Thanks for in insitefull and accurate post

That's because you said it in a very confusing way.

Thats entirely possible, Yet it isnt justification for how people react. Instead of acusing me of not knowing what I am talking about, or insulting me, or claiming to know better when one does not perhaps the idea would be to say they dont understand. That is the adult way of handling things. It is also what this forum has been losing more and more as time goes on.

True, we can never have too much proper behavior, and language, etc.

BTW, what does Tranny Swap King mean? I have a need for a swap, for my 93 Explorer. I want AWD with the five speed automatic 5R55E, for my mail vehicle. Do you know someone who can say what is different between the two generations of the 5R55E transmission? The 2002+ model has a different case, which is available with an AWD transfer case.

It seems we are in the same ballgame. I will take into consideration about the ideas we have discussed when designing an exahust system for my project. This was an enjoyable thread to read thanks to you guys.

Yes, best thread lately. Regards,
