Megan Racing Test Pipe

I've been using a Street Unit test pipe for 20,000 miles. NEVER had a check engine light. But, it still won't fit a 6i, and from the looks of it, they do not have Mazda application anyway
 
1. It won't fit
2. Yes if you delete the 2nd cat it will throw a CEL

Kinda figured that....lol

cool, I'm using the PG test pipe on my MS6. I was just wondering if this Test pipe would fit and work on my regular 6i!!
