Dirty exhaust tips? Car running too rich from stock?
I drove my Z (complete stock) for about 1K miles and noticed that there alot of greasy buildup on the lower part of the exhaust tips. I'm guessing this is resulted from the car running too rich? I would think that stock cars are tuned rich, but that's a little to much right? The AFR would probably be lower then 10 (guessing). Anyone else noticed this problem?
Side Note: Have your guys noticed that for most BMW 335i, the right exhaust tip is always darker/dirty than the left exhaust tip. Im still wondering why.... |
