Message	Mine gets pretty raspy around the 2k mark, i have dupree split DP's, stillen test pipes, X pipe and borla mufflers. I had the exact same setup on another Z w/out DP's and had no issues. The eventual fix may be to go to a high flow cat - keeps me from having to swap cats every 2 years and gets rid of the raspiness. IZCC #8358 1994 Black Emerald Z32 TT 1997 Black Emerald A32
