First, thanks for being my first ever fan. Second, I don't think the FMF Q is the power monger of aftermarket exhausts. The one thing I was very disappointed with was the weight. You hear all these stories of how pounds get shed with them. I was hoping for something substantially lighter. It made a difference, mostly on top, but pretty subtle compared to the nearly free Dave's mods. My stock exhaust also had the welds ground on the header for whatever that's worth.
