My new 914 has gaps between the heat exchanger and the exhaust, which isn't a stock one. Is it supposed to be welded to make a tight fit?
Thanks, Rick

There is a gasket, and you may want to use two for each side.

Thanks, where do you get them?

Any of the standard 914 vendors

get the correct ones for your application. 2.0 differ slightly from 1.7/1.8 versions and late he are completely different. if you're unsure which to buy post a picture of the he currently on your car.
