Alpha Test Pipe
The Alpha comes from the factory with a 3.5 " stainless steel exhaust that flows great. So why replace everything from the cat back, when the converter is the only thing that is muffling your sound and reducing your performance. This test pipe deepens the Alpha's roar and allows the sound of the turbo to come through. At the same time it removes the restriction and increases performance.
