I just had the cherry bomb extreme installed onto my truck, and whenever I'm in park or neutral and push the pedal down I can rack the pipes... but whenever I'm just driving like normal how do I rack them?

 

what is racking pipes? never heard that term...

 

Yeah! What do you mean by "Rack the pipes"?

 

i think he means (Rapping) if im thinking of what he is talking about

 

Rack Pipes or Rapping Pipes I've never heard of either.. Is that like Ceramic coating ?

 

its hard to explain but its the loudness of the exhaust, when mine are at higher RPM's it starts rapping, explaining it is kinda hard, instead of the normal rumble the exhaust gets alot more higher pitch if that makes any sense lol

 

Yea I got you. We call that "cowboy pipes" where Im from. It makes a ridiculous back rap like that of a harley when they get off the gas.....

 

I have found the further back you mount the Cherry Bumb the more of a "Rack" or Snap you will get out of it when you put your foot in it.

The forward you mount it, the more rumble, thrushy noise you will get.

 

wait till the insides get worn out pretty good then youll get that
they have to be worn in kinda sorda they will get louder
