Default Pipe dream?

I was looking through the EFRA rules today and the only thing I found that was measured was the noise level (general rules and 1/8 off-road). I'd always thought a 2013 was a 2013 but if this is indeed the only test done (I know they have drawings as well), there are differences between brands for the same homolagation. What got me started down this rabbit hole was the price differences between pipes with the same homolagation (ie one 086 costing $80 and another costing $35).

We always see xxxx pipe works great with this motor; does it need to be broken down even further (ie by brand) or is this noise test somehow sufficient? Perhaps I missed something in the EFRA rule book (reading it from my iPhone because I cant view the website at work)?
