2009 silverado straight pipes with cats
This is my 2009 5.3 v8 with the stock cats still on and the stock 3" pipe with no muffler or resonator that Y duals into 2.5" pipes with 4" black tips. Ive tried every muffler replace and it wasn't loud enough till i just cut it off. It doesn't have the stupid pop going down the road. Love the sound. It doesn't cause any lights or codes to go off, and will pass all inspections, unless they have a sound limit. FOR THOSE GOING TO A MUFFLER SHOP AND WANTING TO KNOW EXACTLY WHAT TO TELL THE MECHANIC, COPY AND PASTE THIS BELOW. THE SIZE TUBING AND TIPS ARE VERY IMPORTANT TO THE SOUND. The stock single Exhaust pipe was 3" in diameter. Cut off the stock muffler and throw it and everything after away, or sell it. Where the stock muffler you cut off started, weld a 3" in and dual 2.5" Y pipe in it's place. (shown in video) Run the 2.5" tubings out to however you want them to exit (mine were 45degrees in the rear to hide my lift blocks) and attach 4" wide tips, preferably longer than 12". Thanks for watching guys.
