Default Exhaust fumes inside car

Has anyone else had issue with exhaust fumes inside the vehicle? It is most noticeable when the HVAC blower is turned on. I have a 2002 WRX Wagon with the cobb stage 2 kit. So a cobb turbo back and accessport.

Any help is appreciated! Thanks!

You are going to have to get under there and check for leaks. I would start by looking around the turbo area, look for soot.

Yeah, I suppose the turbo back may be the most likely place for an exhaust leak since its aftermarket. I will check out some things and update the thread with my findings as soon as I can! Thanks for the help!

honestly I've noticed that all the subarus I've had have a tendency to have exhaust creep back up to the front of the car. Even my outback does this. I kind of wonder if there are low pressure zones that cause exhaust to come up from the back of the car. It's noticeable for me at lower speeds with only the driver's side window down partially.

Well, since I installed the factory heat shield bracket and a Perrin heat shield, the exhaust seems to be significantly decreased in the cabin if not totally gone. The car didn't come with the heat shield or bracket, so convenient that I needed to I stall one? Maybe so. Though, I didn't really notice any sooting around the area...
