2010 Silverado Flex Fuel Muffler Suggestions.....?????
I want a nice low rumble to my truck, not high pitched. I was told that the flex fuel trucks didn't sound good with a flowmaster muffler. Any suggestions?

It's not the flexfuel...it's the active fuel management that makes it sound weird. I had Flowmasters on mine before I switched to Magnaflow. It sounded alright. It didn't sound good when in V-4 mode and I don't think anything will fix that except turning AFM off.07 Silverado Z71, 6.0L, Turbonetics T-76 @ 10 psi, 75-shot, Comp 212/216 .560, 4L80, Yank 3000, meth injection, Magnaflow dumped, e-cutout, Nelson tuned

Try a Dynomax #17233 Ultra Flo Welded muffler. 3" inlet and outlet. 20" body length. Stainless steel. Rumbly. Handles that 4-cylinder drone just fine.The Cheap-*ss Modder & Thread Killer

screw it just run cats only... with the right tip it takes away the raspy noise that you get from running it with out a muffler the only time it gets anoying loud is when you put your foot to the floor, but if you take it easy it sounds like its got a muffler2000 single cab short bed 1500 w/ 6.0 vortec maxx swap from a 2006 2500, custom intake, slotted brakes, shorty headers, 8mm wires, electric fan, strait piped, 4.5 inch lift, asp pulleys, true dual through body exhaust, built trans w/ shift kit, custom tune by efi alchemy...320rwhp

Check out this thread...
It's a nice set up and you can also hear it on youtube. Perhaps you could PM the one who started the thread and ask them your questions. Hope this helps... I am looking to have a new exhaust system added in the near future, just have to get some headers first... Show us some pics!!!!!!GO GATORS!!!
