From your imagination???

looks like a factory 2.0 muffler, slightly modified. Someone chopped the tailpipe, plugged it, and then went a little overboard turning it into a 911 type sport muffler. I can't stand 4 exhaust tips on any Porsche!

I'm thinking late 356 vintage aftermarket sport muffler.

First guess was right. Stock 2.0 Muffler welded shut, with four tips welded on. I'm with you on tips for looks but I'll bet it sounds fairly mean and flows pretty well. This monster weighs a ton as well.

The stock banana is a boat anchor on the tailend of the car. One reason to switch to a Bursch.
