As per the pic, bought this 2-piece decat downpipe...and was under the impression that the secondary pipe was going to be a silenced section... but it looks very much like a cat to me....with o2 sensor as well.
Look inside the heat shield as it might be a straight through pipe as I believe the Prodrive ones were but had oem heat shields fitted, which made it look like a cat.
If it's not a straight through pipe then 100% cat not resonated section.
As above look inside and see if the cat has been gutted (insides poked out etc )

Good call, I'll get a torch on it later and have a look. I was told it came off a prodrive STI...so I'm hopeful it's just a straight through with heat shielding for effect. And yeah, I know that ref o2 sensor
