My AMG E63 gained 65hp from just the down pipes. They are a major factor in TT hp gains. |
I dynod 640hp on eurocharged awd dyno, that's roughly 744 crank, and that was tuning all day long, I think if you were close to that you would be good, I cant say that without tuning it you would see much more.
