Eric4Nitrous,
So what you are saying is that you have used both intakes at the track and there is a difference?
I think the stock mufflers are better than a set of Flowmasters because my car ran better on night at the track with the stock ones instead of the aftermarket ones. Who cares that the night with the stock mufflers it was 60 degrees colder.
Of course you can rely on dyno number to get a feel for what is better. Everyones car is going to be different in some way or another but you sure would not want to go out and buy something because someone SAID it was better.
I would much rather have a test with all of the variables the same!
