    Driving home from work a few days ago, noticed during warm up that the car was running rich (significant amount of black smoke from the exhaust), went away soon afterward. Yet, when the car was warmed up, and under full throttle, I could smell a significant amount of fumes within the cabin (enough that I needed to open the windows up to get the smell out of the cabin). Are you guys (and gals) getting this too? I feel as though I may have an exhaust leak, so wanted to see if someone else had seen this too. Thanks!

    I developed a small leak too. Can smell when stationary. I have an aftermarket DP though. Havent had the chance yet to really dig into it yet to determine if its the DP/Turbo seal, loose fastener (the upper one is hard to Access and may not be fully tightened) or if something more sinister like cracked pipe or manifold.
