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!

2005 Chevy Silverado Flowmaster Super 50 Series
Flowmaster Force II Cat-back. Super 50 Series Muffler. 17362. Replaced my loud droning turndowns with something more subtle. Took about an hour to remove the old Exhaust and install the new. Uses factory Exhaust hangers and bolts right up! Clamps don't leak as of now. :-)

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.
