new exhaust question??????

i got a new 2.25" Exhaust straight back from the stock headers but now i got a pretty bad power response.it like gargles when i push it some. can that be that it needs to break in or what??? lmk:confused::confused:

you need some sort of restriccion on the exhaust, its a pipe no break in needed, could also be that you have removed all the O2 sensors and the ecu went into limp mode
 
the front o2 is all thats needed. as long as thats in line, your fine. What kind of motor is this? If it's on an NA motor, than it might be to big...
 
yea NA KA with shortty intake and all emissions were removed and all the vaccumes blocked too i have my O2 sensor in though with stock headers...
