   There is a load of FAQ's at the top of this section. If you click on them there will be a "big exhaust thread"
   
   Follow the link on that and it will bring you here

   had a 4-2-1 janspeed with sports c at on my vtr gave me loads of torque over the whole rev range which i'd reconmend on a 8v vtr that tends to have just low down torque.

   4-2-1 mid range power and 4-1 top end power!! Dnt expect to be blown away though, it's jst one factor of the breathing mods, it will feel more like it wants to pull/rev along wit decat!!
