Hey guys, my 957 turbo is due in for secondary decat with stainless steel exhaust specialist tomorrow! Hoping for better sound from the mighty V8.

I thought the secondaries did not have o2 sensor but read they might. Don’t really want a warning light…

Anyone clear this up for me please, will I need sensor spacer or ecu plug in to sort?

 

You can remove the secondaries without issues. O2s are upstream of them

 

Perfect, thank you 👍🏻
