Highly recommend it Ran, with the bmw PE the cold startup is kinda obnoxious but other then that its not really that much louder (I don't get any drone really)
I found cattless dp + PE is very loud and the smell is intolerable for me.
my current setup is cattless dp + N54 midpipe. it may sounds funny to other ppl whereas most of N54 owners try to swap to N55 midpipe.
The smell is totally gone and its quieter. but it's not as responsive as before. I'm thinking to have catted downpipe and swap back to my old midpipe. any thought?
