If your BMW 2002 has developed an exhaust leak your exhaust stud nuts may have worked loose, or even
After having my BMW 2002 garaged for the winter, I noticed that the interior of the car was filling up with exhaust fumes. I started searching for a leaky muffler or hole in the trunk of the car which would have been leaking exhaust fumes into the interior.
I put a Starla exhaust system on my 1973 BMW 2002tii and the car developed an exhaust resonance between 3800 and 4300 rpm and later at around 3200 rpm.The Starla was the suspect, since its muffler was a poor fit…. Many people have had excellent results from the BMW OEM systems, made by either Eberspacher or by Leistritz.
