Re: Slight Exhaust level Change
Thanks for listing the pipe size, I wasn't sure what it was?
So you have no cats & no resonator & the x-pipe completely cleared up the drone?
Awesome that will be my next mod.

I have no cats, H-pipe or muffler. I do have the resonator still installed and it now acts as my muffler. And yes the X-pipe completely cleared up any drone. 
I don't have any sound clips yet but here a clip from another XF with the muffler delete that sound exactly like mine...
