[Mk2] [NA] Changing standard exhaust

[v1xz]

Bought this... Powerflex custom exhaust system for NA
Thought I'd make a documentary plus somewhere where i can get help...




Im awaiting a new gasket for the manifold... Excited...

Decided to take heat shield off to see if the manifold is a match.

**Soak bolts in WD40**
3x bolts on top are easy to get to.
2x 12mm bolts half way down are easy to reach. Mine has rusted away, leaving parts of the bolt still attached, had to use a disc cutter to free it.
2x 14mm bolts at the bottom of the shield, easier to get underneath car. Im fortunate enough to have 2 ramps, you could use axle stands.

My question:
original exhaust has a sensor. New exhaust hasn't.

What do i do?
