Can I ask why you didn't just stick with a stock SVT exhaust and have the mufflers welded in? 2-1/4" piping is the same as stock I believe, and mandrel bent to boot.
I think the tips could come up maybe 1/2" to fill the holes a little more, but it looks great other than that. LoadedSVT's tips look the same, so I'm assuming it's a similar setup. Not loud enough for me though.
