Anyone ever used a Scorpion 2nd Decat Pipe on a Impreza Hawkeye JDM, if so what difference does this make, is the one in the link the correct one....or does anybody have a link for one? Cheers

Jdm only have 1 cat with the lambda in the downpipe.
the pipe you have posted shows a hole for the lambda and therefore is wrong

Are you sure about that???

Yes the A/F sensor (22641) is moved from the manifold to the top of the down pipe (due to twinscroll setup) but the O2 sensor (22690) in the second "cat" pipe is still listed using your VIN.
As to whether it's actually a second cat is up for debate.(but given it's price it probably is)

I had the Scorpion pipe on mine. It made it louder.

Pm sent.... I maybe able to help here do you mean the resonator box pipe work so after the cat but before the Center section
If so I have a new Hayward and Scott section that I bought but took it off after a day belive me it sounds awesome when replaced but
to loud for the area that I’m in.

What back box did you have though?

I had a Prodrive box and while the Scorpion pipe made the system louder, it certainly wasn’t embarrassingly loud.
