ok so as of right now i have a catted y pipe to 3 inch all the way back

i want to take out the y pipe and run separate dumps before the rear wheels

no mufflers/cats/resonators

alot of people have said to get a x-pipe but if im not using any form of muffler and just running pipe from header to exit at the wheel on each side... what would an x-pipe be doing for me?

would i be losing backpressure or does the x-pipe work better for true duals running all the way back?

in essence i just want 2 separate pipes from each header to the exit and want to know if i would be hindering myself at all

need some advice here so i can get this in motion

thanks!

 

They have a Sticky for you called True Duels i have seen some setups in there that have them going all the way back with out using X pipe or a H

 

Wouldn't you get a lot of "rasp" like that? I think the X and H pipe eliminate a lot of that but I could be wrong

 

the midpipe makes a difference in sound and performance. you definitley need the crossover. i went with the H to get the low rumble but Xs are just as good if not better

 

but as of now i just have a 3inch y running back...

i want to run a 3 inch pipe from each header to dump in front of the rear wheels

why would i need a x or h pipe if i just wanted to go from header to pipe to dump???

 

evens out exhaust flow that's why

 

it has something to do with exhaust pulses. i cant exactly remember but i know for a fact that you will pick up power with a crossover vs straight pipes, and i know this b/c i tried it. i picked up like 8hp or so just by adding a crossover to my duals.

 

You will want at least an H-Pipe to even out the exhaust flow. An X-Pipe is known to flow a little better than an H-Pipe. Just think about exhaust running through this H or thisX If I were doing it I would do an X pipe.

 

i have run TDs with no merge, and both H or an X and i noticed the H sounded better and the X was better for performance. IDK what the dif between an H and an X would be with a stock car but i no with my H/C i noticed a little difference

 

no x or h herre that crossover is just extra dead weight....

 

If you want to run a separate pipe for each bank,

....do it!
It will give a very similar sound to side pipes.
Most people get off on sound, not what is 100% efficient or practical.

The advantages of H or X-pipes I've pasted below:-

Balance/Cross-over Pipes

This is straight out of "How To Build Horsepower" by David Vizard
ISBN 0-931472-24-5.
--------------------------------------------------------------------

......."Extensive dyno work & highway testing has demonstrated that a simple crossover pipe -interconnecting the two sides of a dual-exhaust system just after the collectors & ahead of the mufflers- can increase engine power.
The power benefits of a cross-over pipe apply to both street & race cars, but the reason for power enhancement differs in each instance.
In an open exhaust race vehicle with a x-over between the collectors, the pipe transfers exhaust shock waves from one side of the system to the other.
With a street system, the x-over pipe performs an additional function: The x-over allows each side of the engine to partially share the combined muffler flow capacity.
Although, even the most effective x-over will not double system flow, improvements of 25% are common.
Crossover systems can be constructed in several different ways. The single, straight crossover is acceptable when muffler flow capacity is exceptionally high, but a double x-over system will increase performance if the mufflers are restrictive or engine output exceeds 350hp.
In simple terms, the more restrictive the mufflers, the more essential the x-over pipe becomes."
D.Vizard

In Summary:-

..."Prove 100% successful at reducing noise. Anywhere between 1 to 3 dB....
60% of cases on a dyno show a power increase of up to 12hp with 5 to 8 being normal....
40% of cases showed no change in power....
NO cases of any reduction in power.....
...Length of balance pipe is not critical. Dyno test with pipes as short as 18" responded in the same manner as ones 72" long"...

thanks guys... those were the answers i was lookin for
