i have got a sporster custom 2010 looking to put hooker trouble makers they do not come with 02 senser or i can get the 02 senser supplyed but have to drill holes in pipes. i am going to buy a race tuner and heavy breather kit and later on do heads and came what is the option put 02 senser in or not. ps what do the trouble makers sound like dont care how lound an long as thay sound deep and tough like a big twin hoping

Got hookers trouble makers on mine with the 02 sensor bungs. If you remove the 02 sensor, you won't be able to tune the motor with the SEPST.

They are loud and definitely sounds more like a big twin. But will never sound that good. Maybe with a 1200 I dunno??

just put a set of v&h short shots on it . i did 2 years ago .
had to fit a set of quiet baffles in them .
work well ian o2 sensors are there .
