yea but i was wondering if ICS is diff then other compression systems (sorry for making such a noob thread but i've been riding threaded)
No its not different. Inward compression,QCS compression, french id compression, proto ICS, DSA compression etc are ALL ICS compression.
The only types of compression which arent ICS are Proto SCS (Brass Knuckles), Rad HIC compression, and VNC HD Compression.
