August 18, 2004: Is it possible to accidentally work on a car? Last night I was finishing up at work and made the mistake of wandering back to look at the Seven in the shop.
An hour later, I was putting the final touches on a new exhaust tip. I'm not as happy with how it looks as the original but it should both be slightly quieter and will prevent the tire from overheating. Thanks, Ander, for confirming this in my guestbook. A bit of trimming on the side panel for the exhaust exit and the car is getting more and more civilized. Well, relatively civilized.

After some talks with my friends down at Scotty's Muffler, I've worked out a slip-on exhaust tip that should drop the sound level a bit. The track day is under some extreme noise restrictions due to small-town politics - a community across the interstate, underneath an airport approach path have decided that their ambient noise cannot go above 55 dB. The use of the track this Friday is a test to see if cars can use the kart track without causing noise problems. Only Miatas are allowed to take part but we're going to run the Seven. Obviously there is some concern about the side exhaust being loud although I believe it is now at the same level as the turbo Miatas.
