this may have ben posted already but if it was.
i have an 04 mustang gt...i put magnaflow mufflers on it in hopes to make some noise.
it didnt work.
the cats are killing it.
but i cant do away with them becouse the o2 sensors.
can i relocate the o2's on the pipes so it wont trip the mil's sensor.
or do they make a by pass or somthing for this.
any help would be great

 

Magnaflows are pretty silent no? I run them so I should know. You can stick the O2 sensor in the pipe if you know what your doing.

 

Get an off road h pipe.
