Performance Kits and Exhaust

[ETD]

another couple of pennies. yeah, i'll get the intake and exhaust parts someday because i want to connect this and disconnect that for the fun of it. as a mech engineering prof friend said: look closely at the data (dynaflow charts available on this forum). do you thing gm would not have put these parts in if they really performed as advertised so they could sell more cars (because they are relatively cheap).these things only increase hp and such under test conditions i.e. at ~3000 rpm. if you got an auto trans, you won't be driving at that rpm much in "drive". (sorry about the no-caps, too tired up all night with a sick pt.)
