Default No codes if you relocate the O2 sensor...

Gutting your stock ones will probably net you 90% of the performance of an aftermarket DP setup. The other 10% being larger piping.

Only thing needed to be done to relocate the O<sub>2</sub> sensor aft the main cat. Unless you can get a hold of a stock set of stock DPs to modify, expect more downtime as you would have to remove your DPs then get them modified then put them back on.

All aftermarket DPs besides the RS4 DPs delete the pre-cat.
