Header cutouts open and closed a few times on a 2006 GTO LS2, with Kooks' 1 7/8" long tube headers, 3" non catted connection pipes, and 3" full-flow cutout valves from BadlanzHPE.com. Video starts with cutouts closed, and they are opened at about 44 seconds in.

  • Is it bad to put cut outs like before the cats and cat back? That would basically be open headers and i know its not good to run a car with open headers...so is that bad?

  • @protoballa07 It's not necessarily bad to run a vehicle with open headers. I have no cats anyways, my rear O2 sensors are tuned out, and the car has been tuned, so no real negative effects aside from the decibel overload.

  • About how much did it cost for you to do this? I'm planning to get a trans am and do something like this.

  • What exactly do you plan on doing? I added cutouts to my Kooks midpipes, because I did longtubes a while ago. For just the cutout valves and flanges to hook everything up, you will probably spend about $400, but then I had the cost of the connection pipes, stainless steel tubing, and hours of fabrication work on top of that.

  • @JasperJones8887 what's decibel overload?

  • oh ok well ive just heard it wasnt good for it. But yeah i can imagine how loud it is. ive had a 01 z28 with open headers and i only reved it to about 2k and it was still loud as shit!

  • It wasn't necessarily hard, but it depends on how experienced you are. There is nothing very complicated about it, a header install is pretty straight forward, just takes some patience. However, if you want to do cutouts like I did, that take welding and fabricating, which requires a bit of equipment.

  • needs more cowbell.

  • Well if I can do open headers and make it so I can flip a switch to open and close it thats what I wanna do. But if I can't do it there then I wanna do it at the midpipe. I just wanna make it louder and I heard open headers make it climb high end rpm's faster but the lower rpm's slower.
