From chino valley, az Reviewer: From A Customer Own this product - Yes

I HAVE A GMC DURAMAX WITH ANOTHER AFTER MARKET 4in EXHAUST WITH A STRAIGHT THRU MUFFLER (TERRIBLE SOUND). I INSTALLED THE FLOWMASTER 4in MUFFLER USING EXISTING CLAMPS. NOW THE TRUCK IS MUCH QUIETER AND ACTUALLY IMPROVED PERFORMANCE.

serious upgrade
Review for: 50 H.D. Muffler - 3.00 Center In / 2.50 Dual Out - Moderate Sound

From Chicago Reviewer: Anthony Mleczko Own this product - Yes

Bought a 2005 already with a aftermarket system on it. Felt like the truck was louder than faster so I installed a 50 Delta Flow on it. Man WHAT A DIFFERENCE its like the truck found 2 extra cylinders somewhere. I would HIGHLY recommend this as mandatory for the HEMI. Got to let that motor breathe!! If you can spend $700.00 on an exhaust system get the Borla, I can't afford that. This is close as you can get A LOT cheaper. Mellow tone on idle and lets them know you got a HEMI when you push the pedal down yeah right push, more like MASH. Good investment!!
