catless midpipe
Thanks, yeah its a nice piece for a good price.
I originally had a sound performance steel midpipe for a supra (thick and super heavy), which I had to put 2 cats in to pass emissions around here.
When I came across these on ebay I ordered one and use that as a "test pipe". I can say without cats the turbo spools much faster, you can hear it whistling up twice as loud. with the cats restricting the exhaust I dont hear much until its spooled up. crazy how much of a difference backpressure can make.

I have this. It's 80mm so you might have issues bolting this to the stock header (I'm not sure... I've been told the HKS @ 75mm has better fitment to the factory header).
My setup is this: MVP header -> Blitz front pipe. I use a 3in copper 2 hole gasket between the header and the Blitz pipe. There's a slight leak thru one of the bolt holes but it's not annoying or anything.

I am running this mid-pipe with my supra long tube headers that also bolted directly up and I'm getting a CEL for the cat being ,missing and the o2 sensor being unplugged and removed altogether. I planned on having an exhaust shop add an o2 sensor bung to the mid-pipe and then I was going to run a mini-cat simulator and fool my o2 sensor. Does anyone have any input because if you run full cat-less you will have this problem. Also not only is it giving me a CEL it is also making my car run super rich and like crap. If anyone has ran into this problem or has insight please let me know.
Sounds like you have it already figured out. Yes, this is what you need to do to eliminate the CEL due to the missing rear O2
