Cat-back magnapacks+Mac Prochamber=???
On a 2002 5 speed GT with only a Mac cold air intake as a power mod, how much hp could i get by putting a magnaflow 'magnapacks' cat-back and a Mac Pro-chamber.(No tune on the char). What about the torque and were should i get the max gain...low rpm or high rpm. thanks!
Not sure about the power gains but they sound freakin' amazing : http://s79.photobucket.com/albums/j1...t=MOV00207.flv
