For the motor sport enthusiastic Tom also provides numerous specialty
exhaust modifications like the H and X pipe crossovers. The H and X pipe
add low and mid range power to your vehicle and also gives you better
throttle response. Another advantage is that it makes the vehicle significantly
quieter resulting in a mellower, less raspy tone. The idea behind this
concept is to smooth out uneven exhaust pulses from the engine's firing
order, resulting in the improved performance.
The common H style crossover is better at balancing sound pulses between
the two halves, but does little to improve scavenging itself, because
the exhaust gases tend to follow the path of least resistance. In this
case they would flow straight through each pipe rather than taking the
90-degree turn through the H pipe into the other half of the system.
The H pipe crossover is still very acceptable and performs better than
the standard dual exhaust.
The X pipe is superior to the H pipe setup, because in this system the
gasses and have no choice but to intermingle as they pass through the
junction. This promotes the scavenging effects by equalizing the pulses
from the motor. Although the X pipe is the better performer, the geometry
of X pipe makes it difficult to install into some vehicles. In conclusion
a result of more torque, better throttle response and improved fuel economy.
