Maybe this is old news ... but Ford Racing sells a CAI and tuner .... and the estimate 20 RWHP gain on the GT ... wonder if it voids the warranty?

Honestly doesn't even look worth it. $949 for THAT? 2 mufflers and a filter? They don't even upgrade the intake beyond the filter, still would have to use factory tube.

I wouldn't know about the tuner though. I'm an Xcal2 guy

*edit*
Oh, forgot to add. Warranty issue. The M&M act protects you. If it didn't cause the problem, it doesn't void warranty. And even if it did the voided part would only go for that area which was modified IIRC.
