Great sound, better performance!

The stock Switchback sounds more like a metric, so installing a better, richer sounding slip on which also improves performance. Install was straight forward, but the 'slip' needed some tape from a rubber mallet on the mounting hardware. Coupled with a V&H FP4 Tuner, the improvement was immediate. Great sound, better performance... yes, I'm happy!
