New cat back then tune question?

[David Paul]

i have a 2004 Tahoe, 5.3 with 160,000 miles. I need a new cat back exhaust. I'd love a Corsa "touring" exhaust for the power gain, sound and SS construction but they don't make it, only sport that I believe will be too loud for me. What options do I have?
After the exhaust, I plan on getting a tune. Thanks for your thoughts.
