hi guys i would like to know the difference between the downpipe golf 7 gti europe and the downpipe on golf 7 gti usa
because in europe we have 1 catalysts
who knows the cell number of catalysts?

In the repair manuals for my GTI, the second “device” that is on our US down pipes is apparently a particle filter. Now, I’m not sure if I this is true or not, but that’s how it is in the manual. I’ve been curious about it as well.

US/NA downpipe has two cats
EU downpipe has one cat and an OPF (Otto Particulate Filter) where the US/NA downpipe has it's first cat

It’s probably something huge, as in, way bigger than 200 or 300. From some pictures I have seen it’s just one big restrictive mass with minuscule holes. It’s not like the racing ones where you can see the individual holes in the grid.

I own a mk7 gti
euro
on my downpipe I only have a catalyst and no particulate filter
does anyone know the number of cells of the original catalyst?

I’ve seen US listed as 900cell each
