Hey all. I have a new to me 109 I purchased last week. Somewhere along the ling this aftermarket exhaust system was installed. I am not a fan of it and would like to go back to the stock exhaust. I looked and did not see anything that states what brand exhaust this is. From this picture can anyone help me identify them for me? Can they be baffled at all? Assuming I can get someone to trade their stock exhaust for these how much of a job is it to swap them out?
