i want this kit for my truck does anyone out there hav it? is it any good? performance? sound? mpg?

 

I had a Spintech exhaust w/ factory h-pipe on my 99 Mustang GT, and it sounded great. They were chambered mufflers, and rumbled like all hell. I hope those mufflers on that kit aren't chambered though, because chambered mufflers generally don't sound good with an x-pipe. Straight through mufflers like Magnaflow sound much better with an x-pipe.
