Hi all,
I have just fiited a blitz spec nur to my 2004 blob wrx, it also has the last cat removed (not the 1 in the down pipe but the 1 further back). Now we all now how loud blitz's are especially on scoobys, its not the volume that bothers me its the resonating sound inside the car at certain rpm that kills me off! It's a similar notice u get when u have the window down a little bit and go through a tunnel etc.
Can any1 help with this? I really don't want to fork out on sound proving the car, under lay mats etc. Will a bung in the tail pipe help with the resonating?
It's as if its coming from underneath the car tho but the rear box.
I love the noice just not the resonating inside the car!! Please help !!
