Thanks Tom,

Very informative.

I'm going to have a guess that the OE can is Reflective, where the MTC (and any other twin pipe setup) is striaght through, hence an inprovement in performence.

But what of a dual verses single can? both would be straight but I imaging there is some loss of performance (by way of gas speed/pressure or silencing ability) by spliting the pipe into two cans...

I'm trying to understand why a dual can setup is the most popular (for the manufactures), over a single can which should be cheaper.
