At Trax yesterday I noticed jamie GSi and the calibra next to him(sorry didn't catch your name ) both had the SFi boxes removed and power caps fitted in place.
I'm quite interested in fitting one of these.
What are the differences between the Mantzel type that courtney supply for £150 and the one Dave F (not normal) supplies for around £70, other than they look different and you don't get the pipes from Dave?
Is there a noticable difference when fitted?
Is one make better than the other?
