I own a 2005 Ford F150 5.4L 4X4 King Ranch. I just installed a flowmaster super 40 to replace the stock muffler. I kept the stock piping (with the added extra obviously). I was wondering if there were other ways to make more of a deeper rumble. It really only makes a nice sound at 1000-2000 RPMs. I was looking at a catback kit or maybe dumping the tailpipe. I was wondering if its really worth it. It has more sound than the stock but I would love to have more of a presence!! Please post any links of things I should get! Only legal ways please.

 

Loud is overrated. Just ask your neighbors. I have a magnaflow (thanks to the PO) and it is mild compared to a Flowmaster 40, and am tempted on a daily basis to go back to stock.

Run the pipes to the front of the cabin - I guarantee this will make it sound louder.

 

Are you suggesting that i cut the tailpipe right after the muffler? Sorry, I am not very good with vehicles. New to this stuff haha. Maybe not louder but perhaps more resonate and deeper at more RPMs. I can barely hear it.

 

Straight pipe it

 

I would just remove all the piping and mufflers at the headers on back.
This way it will dump out right at your feet and give you some serious sound.

 

and a back massage

 

Twin Thrush Turbo mufflers w/ dual 2.5" side exit rolled tips. Exits right at the bumper. Nice deep bumble and sounds nasty when you get on it. Minimal drone and doesn't scare the neighbors

 

put a 3.5+" x 12" tip on it. 2.5" stock pipe isn't big enough to give any sort of depth to the sound. I have a thread about this on my truck, "just the tip". go.
