lock stock and one and a bit growling barrels

[clasabro]

I noticed my newly aquired 350i had a very clean offside tail pipe. So put my hand in the way and its only blowing about 1/4 the amount the other blows. Looked down the end and can see straight through the back box, pipe looks o.k on the outside. Gas splits into two after the centre box and is symetrical. Before I look inside I want to be sure its not just a wedge quirk. Sent a ferret in for a look see but he got dirty and wasn't speaking to me anymore. Anybody else had the same problem? The gas flow not a ferret with a huff on.

Mine blow about the same but is a custom Stainless job, Like the idea of using a ferret to clean the pipes though, I'll have to borrow one of my brother in law's!!!!!!!!
