Slower with cutout Vs my flowmaster = slower, other questions also

[Crizzled]

I have a 1995 lt1 camaro a4 with a yank 3200 stall, 3.73 gear, long tube headers, y pipe no cats and 3in exhaust. So my 3in exhaust was complimented with a flowmaster 80 series, I was reading that flowmaster doesn't flow well and lots of guys get a cutout so I figured why not I'll get a cut out. So I installed the cutout and went for a ride and the car felt a little sluggish like I lost torque. I'm thinking what... 🙄 top end seems the same. I have the cutout placed after the y pipe by the rear passenger seat area, if anything I thought it would feel faster since air isn't flowing through all those bent pipes and the chambered flows. Before the cutout the car ran 13.4 @ 101 with a 1.8 60 no time with the cutout yet. Now I'm thinking about closing the cutout but feel like that will also hurt performance because of the turbulence from the cutout being closed. now I'm thinking of getting a new 3in pipe all together 😔 I hear cut outs do well with stock exhaust but mines so open.. does anyone have dyno proof of my setup with a cutout improving their times? Looking for opinions
