The Tahoe actually has a 2.75" pipe, I did an exhaust mod too!
As of the muffler it won't sound any louder if its stock, are you sure you the Denali you took it off of doesn't have a Corsa GM Perf. Exhaust.
I know for a fact my Magnaflow is way louder than a Denali stock exhaust, plus I've NEVER in the history of this forum heard of somebody doing a stock Tahoe to Denali exhaust sway?
