I usually source mandrel bent elbows in material of your choice and weld them up together...I would think you'll get better performance and sound with a "Y" splitter then a box.
i wouldnt have belived it, untill I seen it. But its like everything else in this world, its personal preference. deffinatly nothing wrong with useing the Y splitter
It's all about airflow...your hp, torque, and sound is effected by this. With a cummins or any turbo motor, the better the airflow, sooner your turbo kicks in fullboost thus making more torque.
When using 5" pipe I dont think it will hurt it to much
