Does anybody know where I can find dyno info about different exhaust setups. Everybody says Magnaflow is sooooo much better than flowmaster in perforamance but I have never seen a dyno graph comparing the two. I've never seen a dyno graph of either on a stock or moddified car. So if anybody knows where there are some please let me know.

 

Look in Mustangs and FAst fords and also check Mustang 5.0 , in the articles they sometimes have dyno graphs
