Go stage 2 or use 2 spacers one on each read o2 sensor. Highly Discussed topic you should search around next time

Honestly its 100x easier to just go stage 2 tune since you already have the downpipe.

I use a $10 ebay spacer and have no issues with my cbfa. Is the spacer on the rear 02?

We use these on every car that gets spacers. http://store.excelerateperformance.com/vibrant/vibrant-weld-bungs/11619/i-413154.aspx
