Anyone managed to fit the 135i PE to their 128i by simply cutting off the longer pipe?

My thought exactly. There are plenty of 135i PE for sale around the country. It would be easy to cut in the same place as the 128i exhaust and bolt them together with a flange except I think they are different diameter. I don't know how far off the diameter could be. A decent muffler shop could weld them together. I just don't know if it would sound the same. The 135i was designed for higher flow and it could sound like ass.
