22" or 24" magnaflow?

I need some advice guys. I currently have a 40 series flowmaster on my truck. I LOVE the sound and the noise. My neighbors, landlord and my wife do NOT. I figured if I was going to change out the muffler I should try something else. I've been on youtube, but 95% of the clips are 18" body or smaller. I tried searching here but found pretty well the same thing. I want my truck to still have some rumble. My big thing is I need to quiet down the cold starts (I wake the neighborhood at 5am every morning), something with less drone than the 40 is welcomed too. What do you guys think? I need something much quieter, but I don't want to turn heads or **** off the neighbours anymore. Help please
Edit: truck is an 06 4.6

An 18" will have far less drone than a 40 series, and the cold starts will still be rather quiet as long as you don't swap out the cats. IMO 22 and 24 inch mufflers are just too big and don't offer enough for the effort to weld them in.

I should have also said my pipes are stock. I had the muffler welded in and a 4x18 rolled tip on the end. I am NOT touching the cats

If your neighbor is only a few feet away its not going to matter if you do a different muffler. I used to hear my neighbors when i lived in town when they started there expedetion with stock exhaust. Its just part of it.....By them ear plugs!! Roush offroad should help

The neighbors are kinda close. I had a super 40 on my ranger and never had a complaint from anyone. My truck rattles the china in the house and the complaining neighbors are 4 doors down....... I NEED something quieter, but I don't want stock quiet

I just had a 24" Magnaflow SIDO installed and it doesn't make too much of a rumble. I'm happy with it. My wife noticed that I had changed out the muffler though.

18" body Magnaflow will be fine.

Both will be much quieter than a 40 series.

hushpower

add a flowmaster hushpower muffler to your current setup.

I recently put a Magnaflow catback system on my truck and it is a bit louder than I expected. I called Magnaflow and they said to install a small pre-muffler/ resonator. The part they suggested to me was their 4" round 14" long Magnapack. (Magnaflow part number 14419)

I ordering mine soon. Every morning my truck wakes my son up... but I love the sound

(Cat-Conv.)==(Resonator)===(Muffler)=========(Tail-pipe((((

I really think that these newer F150's aren't as sound proof as the prior generation. my '05 seemed much more stable and quiet on the road.

I just installed a 18" with my new kit and I was pleasantly surprised at how mellow the start up tone and idle is. Not LOUD at all. Should be quite a difference than the flowmaster 40.

Well the 18" body would be far better to me. I just don't want to have to change the muffler a third time that's all. I'll hop back on youtube and try and get a sense of the 18" magnaflow compared to the 40 series flow. Is there a big difference between the 4x9 oval and the 5x8 oval? I'm thinking the 5x8 will be a pinch quieter? Thanks for the responses so far

Well youtube was kinda useless... Most of the trucks have 14" magnaflows or magnapacks. The couple of 18" body's I managed to find did sound pretty mellow until it was revved up. By my rough thinking the 5x8x18 maggie should be about 50% quieter than the 4x9.5x13 flow on there right now. Thanks guys

I think you'll be happy with the 18" magnaflow. Are you going SI/DO or SI/SI?

SI/SO I'm a cheap bastard and kept my stock pipes. Aside from a choke down where it unbolts from the cats back it actually looks pretty good. Even the 'y'
