Its not EXACLTY what we wanted(was looking for Hetricks pipe or WRH but both sre sold out :() But Hetricks had this pipe used in really good shape still and said to give it a try.....Im likin it so far... ITs more a top end pipe which he really needs anyhow and with it geared for top and and a modified head to go with the 70 kit it should have much better compression(last head did nto fit properly) Ill know more tomorrow....... :)
