Function of an x-pipe is to synchronize the exhaust pulse by merging separate banks together lessening back pressure and increasing scavenging, in result a horsepower and torque increase from 2-10% depending on the application is obtained through out the entire RPM range.
The x-pipe will lower decibel levels 2-3 dbs for a more quality exhaust note.
H-Pipes
Function of a H-Pipe is to equalize pressure between banks in return the vehicle will gain more low and torque and gain in sound quality.
In Race applications the use of a balance pipe is recommended for sound control and extra volume for negative back pressure.
Y-Pipes
Function of a Y-Pipe is used to increase low and mild range torque and horsepower. Y-pipes are used when tight working area's are a factor.
