Joe, I have had very good response on the 2 into 1 systems on 95 and 103 c.i. engines. The main diferrence between the true dual and the 2 into 1 is the true duals will have better top end H.P., and the 2 into 1 will have better bottom and mid range T.Q. than the true duals. Over all I have heard good response on the new 2 into 1 designs.
Thanks for buying our product!
