I did not get to track my car yesterday. Let me show you why.
Needless to say, I'm a little above the track's 85 dB noise limit at the fence line. Apparently, rust forms inside the muffler when these cars only go short distances for most of their lives, as the muffler doesn't get warm enough to evaporate off condensation that forms inside.
Then this happens.
PSA: Drive your cars for longer distances, especially if you might use them as a race car later.
I'm thinking of using my old muffler as a vase on my back balcony, just to class up the joint.
