Just look at the "what have you do to your truck today" and the "show off your pre 97 trucks" threads.

The tailpipe is a stock Powerstroke piece I picked up at the Barrie Automotive Fleamarket.. for those that know about it, and it's actually close to 3.5" in diameter.
The rest of the pics are the current 5.0 system that uses the same catback with a custom muffler(more on that below) with the Y pipe modified to fit the new Flowtech longtubes that as you can see hang too low compared to the old ones. The muffler is the shell of a Super44 that has been gutted and filled with a straight through pipe and damping material making it much the same as a Magnaflow muffler. I call it the MagnaMaster. It is just as loud as the Flowmaster when you're on it but quiet when you're not and most of the in-cab droning is gone. And the video clips don't do the sound justice either, it's much louder in person and when driving down the road, I'd like to get a drive-by clip made but my good camera died so that will have to wait.

Here's that same truck with the mufflers popped off and straight pipe stuck in their place, just wanted to hear what she'd sound like straight piped lol. By the way I was cruising it with the windows up, only the rear window slider was open, that's how insanely freaking loud it was...

Here's the only vid I currently have of my 94 F150. 302 v8 with stock manifolds, a 2.5 inch walker replacement y pipe, single walker cat, into a 2.5 inch mid pipe, into 2.25 inch tailpipes, no mufflers. Its quite a bit louder in real life then the video makes it sounds...

Hope you don't mind me sharing a vid of a slightly older truck, its my 86 F150 when she was still alive and well. 351 v8, 2.25 inch duals off the manifolds, 24 inch thrush magnum glasspacks, no cats, both pipes exit out the passenger side infront of the rear wheel.

I run ford motorsports shorty headers, stock lightning midpipe, and a borla DI/DO muffler dumped.
