Default Flowmaster descision?

I have a 5.3L with pacesetter longtubes and ORY, and was wondering which flowmaster would flow better and sound better; 3" single in/ 3" single out, or 3" single in/ 2 1/2" dual out? Which flowmaster series is the best also? I do like it loud!

put a 1 chamber flowmaster on if you like it loud. The 2 chamber doesnt flow worth a crap.

i actually had the single chamber flow master with my pacesetter LT's and ORY. It was too damn loud. I just replace the singe chamber flow with cherrybombs 2 chamber elite series. Never thought I would say I bought a cherrybomb, but i couldnt wait to tone down the single chamber. Just figure If i didnt like it then I would replace it later with a magnaflow. I think Im liking the cherrybomb muffler

Id skip all flowmasters...

Brad has on a stock 8.1L its the one that flowmaster suggests for that truck.. you cant hear jack **** inside.. the drone is so bad you dont want to drive it.

He taked to the flowmaster dealer and he said " yea they are all like that"

I have OBX long tubes with no cats with true dual 2.25 pipe and 40 series and its very raspy at 2500...I think the small pipe has something to do with that but I hope with I put my H pipe in it will tone it down...seeing your doing larger pipe it shouldnt have that problem...my truck has zero drone unless Im at 2800 and hold it there...while crusin down the highway I forget I even have pipes on my truck...

my worry with flowmasters is that my truck sounds like every other truck in town.ive got true dual 40 series, with no cats, no h or x pipe. sounds pretty sweet at wot, like you`re really shitting and getting... but you`re not. and im used to the drone, they both dump right behind the cab.
