I've been debating putting on a Flowmaster exhaust system and wanted to know if anyone has any input.
I kind of like the outlaw cat back and the videos and reviews I've read are all good. Without hearing it in person though I don't know if it's going to be obnoxious. The videos don't really give the best representation for that.

 

i have a flow master on my truck it gives a little bit of drone in the cab at the low gears like 1-2 but once ur cruising unless you step on it you hardly know its there

 

Which flow master did you put in?
I don't mind the drone. Can always turn the stereo up

 

I had a Flowmaster installed with Duals it droned so loud that I eventually put on a Dynomax VT system and it sounds so much nicer to my ears. Its pretty quiet in the truck and nice outside but if you get on it it will rumble.

 

i believe it was the super 40

 

I put a super 44 in place of my factory muffler and it sounds good but quieter than I hoped. removed resonator and sounded great but a little drone. I didn't care for it, but definetly liveable even for DD if you don't care.

 

I put a 40 series on my truck sounds good to me loud at 1st but when your cruising highway speed the tones down a lot.

 

I've been thinking about putting on a Super 44 to replace the Afe Muffler that came with my kit. It sounds good but I want a little louder of a sound.

 

I have a very small flowmaster 10 series on my FX4 and at cruising speeds interior drone is negligible. Sounds fantastic under acceleration going through gears 1-3. I find that F150s are quiet with aftermarket exhausts. My old Z71 was very loud with the same set up.

 

Flowmaster 50 series cat-back duals on 2012 5.0L scab xlt 4x4, sounds great on open road and, in town, loud between bldgs
