Initially it felt better as jump in midrange torque but as rpm increased it actually became restrictive due to design and lost quite a lot of bhp top end. Mine was the ABP one.
Got a dyno print somewhere am trying to find will post up later.
As Mattsbobo said a sportcat works and one was tested and made good gains. Think it was the Burk??SP? one.
