I had an hour to spare this evening and installed the Gardner exhaust system on the car. It is amazingly refreshing to come across a reproduction part that does more than you would expect. It bolts up with no problems: everything slides into place and fits perfectly. Even the exhaust clamps slide into their saddles like they were made for each other. When I say it took about an hour I wasn't being sarcastic, the system is that good. I took a little longer due to time spent admiring my own work.
