The hardtuned 1965 Alfa Romeo Giulia Sprint GT

These cars are notorious for sucking the exhaust back into the interior. Taillight seals, trunk seals, and gaskets are all key, but often times not enough. I also tried sealing all of the air gaps with plastic and duct tape, but ultimately the answer for keeping the exaust out was a side exit pipe. Complicating matters, I wanted it to be opposite the driver, which is where Mitch at Mufflerworks worked his magic, and created a unique setup to cross over to the passenger side. It works, when moving the exhaust doesn't suck back into the cabin. (It's not 100% effective idling in traffic, but it's better than the rear exit by far.)
