I coupled my maddad axleback with the perrin intermediate pipe which has a resonator in it, so mine is probably a tad quiter than the typical 3" whisper. I'm still amazed on how quiet the car is now. I miss the sound of the Perrin (which is for sale now

), but I love the silence too.
Next on the list (waiting on some eibach camber bolts and my donor struts) is the RCE Black/Koni yellow install!!!
