Wow nice! A lot louder than I expected. Got a take video of you hammering down?

I drive mine way harder than I should because it sounds good lol

All you wondering about the GM Borla 6.2L exhaust for the Sierra/Silverado it is 3" pipe from 3rd cat to muffler with only the ball flange being 3.5".

But even at 3" vs stock 3.5", it flows better

Would actually say the Borla and stock flow the same based off the boost gauge, it didn't change from one to other. It only dropped once I installed the Magnaflow 3.5i/4o

I saw a 5hp bump going from stock to Borla

Got the borla installed on my '17 tahoe. It's too quiet for my taste. Up for sale if anyone is interested, only 270 miles on it. Comes with black tips.
