I have this exhaust and love it. Nice deep, throaty sound. There is definitely drone, but it doesn't bother me one bit. I wish the tips were welded on like the one for the FK8. The benefit is you can place the side tips where you want. I have them sitting back from the center tip.
You could also get the Quick Jack blocks made for pinch welds.

For the charge pipes, I was thinking $315 shipped. As for the intercooler, I am open to offers because I would want to put the shipping cost into the mix.
