I just installed a poliars pipe, quiestion is at the dealership I bought pipe from said it came with a quiet core, didnt see anything in the box, or is it installed from factory,, did not take end cap off to look,, came here first to pick fourms brain ,,, called dealership, they wernt sure if it came alredy installed or not they are checking????? I was told that the pipe will meet 96dcb is this with or without the quiet core ???????[img]i/expressions/face-icon-small-confused.gif[/img]

 

I assume that it is already installed.........they are a really quiet pipe anyway. I think they are a great pipe though(and many others don't)........but if you tune it right, and have other mods to accomidate it, you'll get power from it. What else have you gotten for your pred?? Any carb or intake mods yet??

 

Mine was not installed. And I did not use it. Just get the turn down tip from Doug....I think you will like it alot better, it has a deep tone.

 

Are we talking about a Predator Pure Polaris/ White Bros silencer? [img]i/expressions/face-icon-small-smile.gif[/img] If so, the spark arrestor/quiet core is simply a plate with a circular perforated pipe welded on it. If you're trying to keep the noise down, it's one of the best units. And with just a bit of experimenting, you can gain some power also. Please correct me if I'm wrong, but Doug's turn-down would be a great choice for closed circuit, non DB tested racing. I'm thinking it would push you over the 96 DB range which you seem to be looking for. Any questions Nicholas Cycle always shoots straight answers if you give them a call.
