Default That Old Black Magic!!!

I just spent a couple of weeks and a few dollars in getting the car (‘91) ready for the summer and I noticed there is a noticeable amount of exhaust residue on the two outside exhaust pipes. I did the standard change: plugs, oil, tranny oil (6spd), radiator flush and new coolant and Purple Ice added. The car seems to run fine, as a matter of fact, it is running as good as it ever has. I did not change the gas, so it is still running on the same fuel as last year. Any suggestions?

I would dump a can of Sea Foam in the tank and run out the old gas.
