So, I have a couple simpler questions. Kyle seemed to suggest that if you haven't done anything to your car yet...don't. But for those of us who have, I'm curious as to why there would by any issue with for example HFC's. I understand the headers, but isn't a less restrictive exhaust good no matter what..or is just a tuning thing because they aren't testing the car with these particular types of setups? And for those of use who have the Gen 3 intakes, what's the best option since we gotta rip 'em out
