MBRP ARMOR LITE / TOUR PROFILE. MBRP PART # S5070AL. Your vehicle should have sounded this good from the factory. 2011-2013 CHEVY SILVERADO / GMC SIERRA 1500 6.2L V8. 2011-2013 CHEVY SILVERADO / GMC SIERRA 1500 6.2L V8 EXTENDED CAB WITH 6 1/2' BED & CREW CAB MODELS.
Very satisfied with the quality of this exhaust system. Fit right up. Took about an hour to install after removing the old system. I used this to replace a 'muffler delete' type of setup. Comparing to a muffler delete, this keeps a good deep tone, it's a bit quieter at idle, a little louder during moderate load from the low to mid of the rev range, and quieter (more refined tone) during hard acceleration / high rpms.
I personally will be looking to replace the muffler to quiet it down a bit more since I'm in a quiet residential neighborhood, but if you're looking to for an affordable system with good sound and volume, this is the ticket.
