Saab 9-3 Gets 3 Inch Open Downpipe Install LOUD!!!

One of the easiest ways to increase horsepower out of a Saab is a tune. But to take advantage of more aggressive tunes, you will want to cool the air entering the engine, or increase the flow of the air exiting the engine. Here, we install an increased diameter downpipe and removed catalytic converter. Now we are one step further to increasing more power. Not the cheapest mod, but definitely not the hardest.
