This is a noise level question. I have the dual N1 muffler catback system. I was using 2 hollowed precats and a new main cat with it but it was too loud (that 3k drone on the highway everyday got old quick). I now have only one hollowed precat and its nice. Im concidering the RB header w/ presilencer to replace my cats because the precat im using is falling apart and making a nasty rattling noise at idle and for better performance. Does anyone have this setup or have heard it? Will it be louder then just running the main cat with the mufflers?

 

even replacing your precats with a header is still gonna make more noise if you are getting rid of your main cat welcome to a whole new level of loud....it will be so loud that you cant carry on a conversation in the car driving

 

I have rb presilencer and header

Its awesome and it sounds great.

So far that's the best mod I've got.

 

its gonna be pretty loud. sounds cool as hell though.

 

theres goes that idea...thanks guys
