Accidentally ordered the 16" Spal fan I need while trying to order some 3" 180 degree bend to repair the dented exhaust on my S3. Didn't realize it was in my cart on Summit when I ordered the exhaust pipe.

Going to cut out the dented spots in a bit of a pie cut shape, then weld in new metal. Should be good practice for when I need to build the exhaust on the E30.
