i have heard of people selling their invidia exhaust with some kind of modification to the mid section to reduce the loud drone sound....can someone tell me what modification this is and how much it would cost??

im debating with the hks and invidia exhaust right now so i need to know asap. thanks in advanced

 

bump, im interested with what this is about

 

Probably talking about removing the stock resonator from the stock system and welding it in place of the Invidia resonator. Havent heard one like this, but to each his own. I like my Invidia just the way it is.... in' loud!!

BTW - a decent muffler shop would do this for you for under $50.
