Booyakasha!
I had their catback on my first car (SVT Focus), and it was a great piece of work. My dad had their Route 66 catback on his Vette for a little as well. Some might not be familiar with this company, but they certainly make some great exhaust products. I have YET to see a S197 with their axleback.
