Guys, the dyno sheets are uncorrected. This is one reason for the high numbers.

Its probably more like 25hp (tops?) for exhaust, plates and charcoal. Thats what I would think makes sense, but this could easily be argued both ways.

I would agree with one thing, the car is faster with charcoals out and plates in places. Charcoals would restrict airflow, and plates would stop hot air from entering the intake. These are defiantly power gains. How much? We could go back and forth all day. To me, all that matters is these are easy and quick mods to do.. and you get a power increase. Really, thats all that matters (to me atleast).
