04 Chevy Silverado 5.3L Flowmaster 40 series

My 2004 chevy silverado Z71 5.3L with the flowmaster original 40 series two chamber muffler. si/so Exhaust. All i did is i swapped out the old muffler and put this one in to replace it with additional piping of course. Which means the piping i believe is 2 3/4. Enjoy!

Flowmaster 40 Series Dual Outlet - 2001 Silverado
Not to be that guy, posting my truck on youtube, but figured I'd put this on here for people trying to find an Exhaust they like. Truck is a 2001 Chevrolet Silverado 1500 LT with 5.3L V8 engine. Fabtech 6" suspension lift if you were curious. Flowmaster 40 series Exhaust with dual outlet. NOT a true dual system. Couldn't afford it at the time, but would like to upgrade someday.. maybe. Update: Getting new cats here soon and probably going to straight pipe from the cats back when I do. I'll upload a new video of that when I get it done.

Just got new hedman hedders installed and removed the x-pipe. Sounds much better and the video doesnt do justice on how deep it sounds. love it. I did all the bodywork my self, i got in done in just two and a half weeks and spent over 24 hours in the paint booth painting the two tone.
