With my testing I have found the single tip is the optimal exhaust setup for the biggest performance gain for your lgt. A turbo car has no need for a y-pipe and the dual-tipped exhaust setups "fork" in the exhaust stream is a significant bottle-neck, expecially when reducing to 2.25" pipe/mufflers. As stated, Less backpressure equals more high rpm horsepower. It doesn't necessarily mean louder as this is a function that is detemined by the muffler itself.
