I have a 2011 sierra 1500 4.8.

I recently installed the mbrp installer series, 3" cat back to dual 2.5" out, 3" roller tips. it sounds good around town, but the higher rpm sound is not loud, the engine overpowers it volume wise. At low rpm, the rumble is nice, but on highway, 1650rpm, (100km/62mph) the drone is someone excessive. The drone mellows around 70mph, and from there up its tame. Nice little rumble all the way up.
