Exhaust fumes Smell inside of FD? Normal a bit?
 

Never rode in a modified RX7, but my friend has one and the cabin reeks with exhaust fumes.

He says its normal because he is running rich but wouldn't the smell indicate a exhaust leak of somesort in the engine bay?

The fumes are a bit intense, just don't know why it's coming into the cabin of the car?

This is the same issue I had when I rode in another car (ae86 with a FC engine swap). The fumes of the engine comes into the car.

Trademark Rx7 "new car smell".

Especially if he's running open wastegates and/or no catalytic converter. Everytime I come home from an event, the first thing my wife tells me is "head up and take a shower." :)
