Exhaust smell in drivers seat - anybody else?

[BeardBros]

I was wondering if anybody else had this issue. When the top is down and I do a hard acceleration from 0-60 I can smell the exhaust in the drivers seat. It fills up the interior and takes a little bit to dissipate. I imagine a vacuum is created from the rear of the car pulling the exhaust up into the driver area. This is only under hard acceleration, everyday driving poses no issue.

I bet you have the stock air intake in your XLR. Under hard acceleration, the stock air intake (stupid engineering) does not allow enough air to enter the engine a that moment and a little partially unburned fuel is entering the exhaust system before the ECU can compensate.

turn the interior air vent fan speed on high
