as big as possible to minimize back pressure. the backpressure created by the turbine/housing is high enough!

If a 5" mandrel exhaust can fit under our cars.....go for it. Just like stated above...the exhaust turbine already creates enough backpressure as it is.

Certainly the bigger the better, but if you want to put mufflers on, then you're pretty much limited to 3". Also 3" tubing is the largest readily available. This makes it the most cost-effective size. Check the classifieds for available systems.
