When I bought my truck it already had a forzaflow muffler on it. The muffler started coming apart at the welds. I removed the whole set-up and put a 20" (I think) extension on it to move the pipe end away from the cab a little. Here's some pics of it and some vids of the sound it has. I still have all 4 cats. 04 4.6.
This set-up is only temporary until I get a Magnaflow. I know it doesn't sound the best but no muffler sounds better than a rattling muffler. Just thought I would share.

jeeez thats loud as hell in the cab

 

Sounds awesome inside, like a Dynomax Bullet. Whats up with your 4wd switch on the dash?

 

nice, but dang dude that 'brow is way illegal hahaha oh well if your gonna do it, do it right! thinkin maybe 10% on my fronts along with the 5% on the backs i already have

 

Sounds mean dude, I'd be tempted to leave it like that! Glad to hear you're considering Maggies!

 

Thanks for the compliments fellas. Darren I have a 2wd so the 4wd switch is a "change holder" (worthless). I think it sounds mean as well, but my g/f complains about it. I had a Maggie on my 04 sierra and loved it, so that is my first choice of muffler. I am going to go with a Maggie 11366 like Darren has and going to reuse my old tip (3.5" stainless rolled tip) exiting in front of the rear pass tire. I think sometime next month I will be able to order my Maggie. Ill post pics and new vids when I get it done.

 

Ah ok. And good choice on the 11" body
