So I had a rattle in my exhaust,(of my ek) i got my cat cut out... that wasn't it. So i got it up on a hoist and discovered it was my resonator... so i got that cut out. after the cat got cut out it sounded deep and actually i really liked it. after getting the resonator out it sounds sooooo bad. at about 3k it sounds like a cross between a bubble blower and a lawnmower... needless to say I'm getting a new resonator
