true duel exhaust question ( its not in the sticky! ) ok i got custom true duels run right now
i put the bullets closer to the front of the exhaust, not like most typical true duels ive seen run on f bodies that are at the end and then dumped.
i want to put in a H pipe.
does it matter if its behind the mufflers? will it make any difference at all?
i usually see x or h pipes in front of the mufflers though.

This has been debated before and the consensus was that the crossover pipe should always be before the mufflers. I believe it has to do with the exhaust scavenging effect and the way back pressure is built up. But I'm no engineer.

An H pipe helps equalize the exhaust pressures between the two banks of tubing as the hot gases and sound waves travel down the tubing. This, in effect, relieves the exhaust pressures as they travel through the H tubing, generally creating an increase in torque. This will also give an added sound reduction when the sound waves combine inside the H tubing.
An X pipe will actually help to scavenge exhaust pulses from one bank as the opposite exhaust pulse passes through the X, thus creating a vacuum effect at the valve, resulting in a cleaner burn in the cylinder. This generally equals added torque and, like the H pipe, a reduction in sound as the sound waves combine in the X pipe.
I'm more of an X pipe fan. Either way, they are typically installed between the tail of the tranny and the axle, before the mufflers.
