I had my Stromung installed today. I ran into a couple of issues though.
The cat must be positioned slightly towards the rear of the car on the Australian 316i, in comparison to the 318ti. The muffler fits fine, but the piping that connects the muffler to the cat was too long.
My muffler shop had to trim the piping down, and install a replacent flange, so it would fit in between the cat and the muffler. Other than that small issue, installation went great.
However I am a little disappointed with the exhaust tone. It seems a little quiet/similar to my old sports exhaust. I can tell the difference when the revs are higher, but I expected a more noticeable difference in the overall tone. Will the tone change once the exhaust is broken in?
I'm very happy with the look of the stromung though. It looks great!
Did cutting the flange and shortening the pipe, and then installing a new flange on the shorter pipe have any effect on the tone? It doesn't really matter because it was either that, or no stromung
but I'm just curious.
