Does any one know where to find PC map for f4i M4 slipon????
Dynojets website does not have dick for the M4 f4i. Any help would be appreciated.

 

The trick is to find out the diameter of your M4, inside diameter known as the core. Then the length. Match that to one they have a map for. I looked up M4 exhaust but they do not list what size core they use.... my 2bros has a 2.25" core. Most are around the 2" area so any slip on you pick from the map database will get you close.

 

Thanks Doncollons, I will research the measurements and find a similar pipe map.
