Yes, this was my first time. I looked at a dozen or so brands before deciding on Borla.

What made you choose this particular product?
One of the cheaper exhaust systems out there; was torn between this and the AWE Track exhaust, but chose this one because it seemed louder.
Is this your first time buying from this brand? Did you consider other brands?
It is my first Borla product. I considered Corsa, AWE, and Neuspeed. The Neuspeed catback sounded great, but it was over a grand.
