I'm confused. My Ti4 bolts to the subframe, clamps to the header, hangs from the clamp on the can, and has springs to hold it to the midpipe. Used with the Power Bomb, the system makes a big difference in spreading power out across a wider range, and gets rid of the little sag/hit thing at 8000.

Yours must be missing something...?

it may be a different kinda power or whatever but the procircuit is desinged to work with many different head pipes
