I'm pretty sure that they were also heavier than the NA one...
why because NA bmw owners love to put euro this euro that on thier mod list .

Ive gutted both mufflers and the EURO has a top 3 roll pipe layout whiles the US has only 2. SAME diameter on the inside. if you look at it its more it seems to me that they did 3 pipes to reduce the noise the motor puts out. not horse power. so i dunno why people thinks its light. if anything it alittle heavier.

If op cuts out the cuts out the smaller flanges on the pipe, the pipes turns into 60MM all the way thru.

I doubt he will loose any power at all with the muffler, but then again i'm not an engineer so what do i know...
