Hello guys,
As headers for the F are being tested to see which leads to the most notable gain, I am wondering if the addition of headers will increase interior resonance when running an aftermarket exhaust? I want to put up my windows and enjoy Lexus sovereignty, and be able to roll down my windows and hear it roar. I plan on running a Joe-Z intake and exhaust with either the Sikky or Elite headers. If resonance has been a concern for some of you running an exhaust etc, did you counteract by using sound dampening materials? Any thoughts?
